The default password is "dell" without the "".
I recently ran a DSET report on an older server. Dell DSET is their debug utility that pulls hardware specs but more importantly hardware logs. So when your old PowerEdge has a blinking amber light you can run that report and figure out what's going on. When you run DSET it places a zip file on your desktop. This has a small HTML app that has the report, it looks a lot like OpenManage. In the report you will find the hardware logs and what is going on with the server. When you extract the file use the password dell.
Trying to add the local administrators group to a SQL server with sys admin (sa) server roles? Getting the error below? I have a very simple fix.
Windows NT user or group 'COMPUTERNAME\Administrators' not found. Check the name again. (Microsoft SQL Server, Error: 15401)
Instead of adding "COMPUTERNAME\Administrators" change it to "BUILTIN\Administrators" and it will work just find. Just erase your computer/server name and replace with BUILTIN.
This fix should work for SQL Server 2005, 2008, 2012, and 2014.
How to fix – WordPress Upgrade Download failed. SSL certificate problem: unable to get local issuer certificate
Getting this error when trying to upgrade WordPress?

1. Download the cert.pem file from here. Right click on the link and click save link as.
2. Place the cert.pem file in your php folder.
IE: C:\Program Files (x86)\PHP\v5.5\cacert.pem
3. Edit the php.ini and search for "curl". Edit the curl.cainfo line with the following.
curl.cainfo = "C:\Program Files (x86)\PHP\v5.5\cacert.pem"
Save the php.ini file.
4. Now try your upgrade again. I didn't have any issues after performing those steps.
With virtualization on the rise we sys admins find ourselves managing a lot more server than normal. Gone are the days of managing a couple racks of pizza boxes. Instead one of those pizza boxes may hold a hundred virtual servers itself. And with so many servers, and clients doing the same fun things, we find ourselves looking into the random "my server rebooted why?" question.
When investigating a reboot you can search the system event log for the event ID's below. Each one corresponds to a reboot and will help determine why. And after you find the actual reboot you can check the rest of the events around that time to see if anything lead to or caused it. For example windows updates, or a BSOD.

I work a lot with DFSr because we use it to keep some web farm replicated and some of our customer's private farms. I can tell you it sucks, it always breaks, and it's very hard to maintain. Although I'll caveat that by saying we probably shouldn't use it for web farms with millions of little files. Seems to work fine for AD. Anyway, this is the most common issue you will run into with DFSr, the unexpected crash or shut down. Both the nodes this occurred on did not crash, in fact they didn't even reboot or shut down. But that doesn't matter, DFSr still crashed. Below is just one example and the fix for it. It's obvious from the event what you need to do, but lets review anyway.
The one thing you HAVE to remember is to leave it alone. Do not touch it after you resume replication. That's the #1 mistake I see people making with troubleshooting DFSr. Either rebooting the server or restarting the server. DFSr keeps a journal (database) of all the changes to the replicated folders. You can't just restart the service or reboot the server to fix this. That's like trying to restart SQL to recover a corrupted database. Instead you need to recover that journal, which fortunately Microsoft tells you exactly how to do in the event log.
To get to the event log go to Control Panel --> Administrative Tools --> Event Viewer --> Applications and Services Logs --> DFS Replication.
Event ID 2213
The DFS Replication service stopped replication on volume C:. This occurs when a DFSR JET database is not shut down cleanly and Auto Recovery is disabled. To resolve this issue, back up the files in the affected replicated folders, and then use the ResumeReplication WMI method to resume replication.
1. Back up the files in all replicated folders on the volume. Failure to do so may result in data loss due to unexpected conflict resolution during the recovery of the replicated folders.
2. To resume the replication for this volume, use the WMI method ResumeReplication of the DfsrVolumeConfig class. For example, from an elevated command prompt, type the following command:
wmic /namespace:\\root\microsoftdfs path dfsrVolumeConfig where volumeGuid="32A74A78-0B49-11E2-93EE-806E6F6E6963" call ResumeReplication
You will need to run the command given in step two from the event in command prompt as administrator to resume replication. Remember that each node in the DFSr replication group has a different GUID. Get the command from event viewer on each node and run it. Example below.
wmic /namespace:\\root\microsoftdfs path dfsrVolumeConfig where volumeGuid="32A74A78-0B49-11E2-93EE-806E6F6E6963" call ResumeReplication
After you run it you will see Event ID 2212 in the log.
The DFS Replication service has detected an unexpected shutdown on volume C:. This can occur if the service terminated abnormally (due to a power loss, for example) or an error occurred on the volume. The service has automatically initiated a recovery process. The service will rebuild the database if it determines it cannot reliably recover. No user action is required.
You may also see Event ID 2218
The DFS Replication service is in the second step of replication database consistency checks after an unexpected shutdown. The database will be rebuilt if it cannot be recovered. No user action is required.
Now you just need to wait for the database to recover. Depending on the amount of files and how long it has been down for it can take a few minutes, several hours, or even days. You MUST leave it alone. Do not reboot the server or restart DFSr. That will simply start the process all over again.
Once it is fully recovered you will see event ID 2214.
The DFS Replication service successfully recovered from an unexpected shutdown on volume C:.This can occur if the service terminated abnormally (due to a power loss, for example) or an error occurred on the volume. No user action is required.
Once you see that event you are good to go. More info in this MS KB.

This is a very simple script to add a local administrator. You always want a backup Admin to get into a computer, because the "Administrator" should be disabled after all. This is a simple script I use to create one that also generates a password I can store somewhere, like keepass. Here is what it does.
- Generates a 32 character complex password.
- Creates a local user.
- Adds the user to local Administrators group.
- Sets the password to never expire.
- Spits out the password to the console window so you can copy/pasta to keepass.
Add-Type -Assembly System.Web
NET USER username "$pass" /ADD /y
NET LOCALGROUP "Administrators" "username" /add
WMIC USERACCOUNT WHERE "Name='username'" SET PasswordExpires=FALSE
Write-Host "$pass" -foregroundcolor red -backgroundcolor yellow
Make sure to replace all the "username" (highlighted in red) with the username you wish to create. I use this at work to create a standard backup admin user for servers. It's always the same username with a different password for each server.
I realized this doesn't work with the execution policy set to restricted. So I made a bat file that runs it from your desktop after setting the execution policy to unrestricted. What I do is copy the two files to the desktop of the server (you can do this in RDP for any server 2008 or greater). Then right click on the bat file and "run as administrator". Here is the script for the bat.
Update deuce. Per reditor's suggestion I took the command to change the execution policy and instead bypass it.
powershell -ExecutionPolicy Bypass -file %USERPROFILE%\Desktop\name-of-your-ps1-file.ps1
In a bind for disk space on a MSSQL server that you cannot restart? Here's a way to force a shrink of the TempDB if that's your issue. Be aware this can negatively impact performance since you will be clearing the execution cache for the server. The cache that SQL uses to store execution plans after they are compiled. Meaning they have to be recompiled. But working for a small host with shared database servers that CANNOT go down during the day I've been in this bind. This is the script I found to fix the issue.
-- Shrink tempDB data file
DBCC SHRINKFILE ('tempdev' , 1 )
-- Shrink tempdb log file
dbcc shrinkfile ('templog' ,1 )
This won't always work the first time, so just keep executing it until the TempDB goes down. I usually have to run this up to 10 times before the TempDB gets down to less than a 100MB. By default the TempDB should be around 7MB when it starts. Also. restarting the SQL server should empty the database and re-intialize it so to speak. Each time you start SQL server the TempDB should be about 7MB. Of course you should probably figure out what is filling your TempDB, but when you have 700 databases on one MSSQL server and you don't control any of them or know the developers, that's easier said than done.
How to increase the number of concurrent RDP connections in Microsoft’s remote desktop connection manager
An issue that has been plaguing me for years has been the number of RDP sessions I can connect to at once in Microsoft's remote desktop connection manager. RDman is an older piece of software that is simple and easy to use. It's also something we use at work every day. The problem is that MS hasn't updated it in a while and it's x86 (32bit). Each session takes up a decent amount of memory and once you get to the 1GB mark, you start getting errors like this.
Error possibly involving 'security settings':
Error HRESULT E_FAIL has been returned from a call to a COM component.
Error possibly involving 'server name':
Attempted to read or write protected memory. This is often an indication that other memory is corrupt.
Those errors usually go away if you sign out of a couple sessions, then you can sign in to more. But there is always a limit, anywhere from 6-10 connections at one time. Except that you cannot sign into the server that gave you the error when trying to connect.
One very simple solution is to just open multiple instances of RDman, but you're still limited to only 6-10 RDP sessions at one time. So how do we connect to more?
The problem is actually pretty simple to solve, if you have Visual Studio.
1. First, open the Command Prompt for VS2012. Or whichever version of Visual Studio you have installed. I happen to have 2012 since we have a dev on staff and we always have the latest license. Yay. Here is a link to how to get to the command shell for various operating systems.
2. CD into the directory where RDMan is installed. Most likely that is:
C:\Program Files (x86)\Remote Desktop Connection Manager
Your command should look like:
C:\Windows\system32>cd C:\Program Files (x86)\Remote Desktop Connection Manager
3. Now type the following command into the prompt:
editbin /LARGEADDRESSAWARE RDCMan.exe
4. You should get something like below.
C:\Program Files (x86)\Remote Desktop Connection Manager>editbin /LARGEADDRESSAW
Microsoft (R) COFF/PE Editor Version 11.00.61030.0
Copyright (C) Microsoft Corporation. All rights reserved.
5. That's it, now you should be able connect to a lot more sessions. Unfortunately this isn't unlimited so you still can't connect to 50 at a time. My max seems to be about 16 sessions at one time. But that at least allows me to open a couple instances so I can get to various environments. Where I work we have some complex Clouds that have 20 or more servers and on patch night I often need to connect to a lot of them at the same time. Especially for management purposes so I can gracefully fail over services, etc.
If you want to skip all this, or don't have Visual Studio, you can download the RDMan I already edited. It should work. Click the link. Remote Desktop Connection Manager
Another alternative is a different remote desktop connection manager. One I have played around a little with is Terminals. It's free and open source. I'm not sure if it has the same limit, I haven't added enough connections to test it out. Find it here. Make sure when adding connections for 2008/2012 you check the box under RDP --> Extended Settings --> Enable NLA Authentication. (If you are using Network Level Auth, which you should.)
Recently ran into an issue with a Poweredge r620 and iDrac. The server was up but giving a memory error and I couldn't get into iDrac. This is the error I saw when trying to login.
RAC0218: The maximum number of user sessions is reached
Very frustrating when I knew there was no one else logged in. A brief search online revealed that we can reset iDrac through SSH, but that didn't help since even SSH gave the same error when trying to login. The server is in a data center and I avoid the data center like the plague. I know there are some sys admins that just love the DC, the rows and rows of servers, the unbearable noise, the too hot and too cold isles. Maybe I'm old, or I've been doing this too long ...
If the OS is working you can use a tool in Dell OpenManage to reset iDrac remotely.
1. Make sure you have Dell OpenManage installed on the server. Download here.
2. Next open a command prompt as Administrator and CD to "C:\Program Files\Dell\SysMgt\idrac".
3. Now run the command "racadm racreset soft" (without the "" of course). racadm is the iDrac CLI admin, racreset is the subcommand, and soft is the parameter. This particular subcommand has 3 different methods to restart Hard, Soft, Graceful, and you can also delay the restart. I recommend that you start with a soft reset so you don't lose your settings. I imagine a hard reset would remove your login info, TCP/IP settings, etc. To be honest I haven't tested it to find out since the servers I have are in production. You can find more info here.
- A hard reset resets the entire RAC and is as close to a power-on reset as can be achieved using software. The RAC log, database, and selected daemons are shutdown gracefully prior to the reset. A hard reset should be considered as a final effort. PCI configuration is lost.
- A soft reset is a microprocessor and microprocessor subsystem reset that resets the processor core to restart the software. PCI configurations are preserved. The RAC log, database, and selected daemons are shutdown gracefully prior to the reset.
- A graceful reset is the same as a soft reset.
- The user is allowed to select how many seconds of delay occur before the reset sequence is started. A valid delay entry is between 1-60 seconds. The default is 3 seconds.
4. After running the command you should see the message below.
RAC reset operation initiated successfully. It may take a few
minutes for the RAC to come online again.
5. Give it a few minutes and then try and login to iDrac through the web interface or SSH. I was able to after running this reset.
6. If you still cannot login you can try a hard reset. Run the command "racadm racreset hard".
7. If that doesn't work, there is one last option but you'll need to physically access the server. Shut the server down then pull the power from it. Make sure there is no AC power to the server. Then hold the power button on the server for 30 seconds. This should completely reset the iDrac. You may need to reconfigure your login information and TCP/IP settings.
The very first time I got serious about computers was when I decided to buy a video card to upgrade, so I could play Delta Force. I don't remember exactly what I had at the time, in fact I don't even think it was my PC. I'm pretty sure it was my parents PC, and it was an ugly little HP or Compaq that had IGD and only a PCI slot. So my first video card wasn't even AGP Not that it mattered since I had no idea there was a difference at the time. I just walked into CompUSA and bought something off the shelf. And that something was a Diamond Multimedia Stealth III S540 PCI 32M. The PCI was for the PCI slot, and the 32M was 32MB of RAM. Which was actually twice what other video cards had at the time like the Nvidia TNT and Voodoo cards. And I could play Delta Force, and Delta Force 2, and it was great.
And I still have that video card. And it still works. And I will love it forever and keep it forever because it is the birth place of what I do now.
Along with those pics I found some related links. Of course no one reviewed the crappy little PCI one, and the card wasn't that great.
