The hosting venue has changed to serve you better.
I’ve been battling an issue for a few days now and finally stumbled upon a workable solution via PowerShell.
One of my customers has an existing Exchange 2007 deployment. The OWA instance is configured to only use NTLM authentication. ExRCA (http://www.testexchangeconnectivity.com… [ Continue reading ]
So, you had a bit of nasty malware. You’re almost back to square one, but have now found yourself in the unfortunate position of having missing services–specifically the Background Intelligent Transfer Service and Windows Update services.
Never fear. These, too, can be recreated in the event that your System Restore points are borked. … [ Continue reading ]
Tonight I found myself recovering a VM on a Windows 2008 R2 cluster connected to an MD3000i SAN. To make very long and painful story short, it appears that someone applied a series of Windows Updates and then a Dell DSM update that screwed up the multipathing.… [ Continue reading ]
In case your Exchange admin life wasn’t difficult enough, you can always have this problem, manifested with the following symptoms:
Classic tactics such as restarting the server or right-clicking the queue and selecting “Retry” have no effect.… [ Continue reading ]
During an SBS deployment, I ran into a few machines at my customer’s site that were running Windows XP Media Center Edition (MCE). As most of you know, the only machines that are technically eligible to join a Windows domain are “Business” class operating systems, such as Windows XP Professional, Windows Vista Business, Windows Vista Enterprise, Windows 7 Professional and Windows 7 Enterprise (although not technically “business” class, Windows Vista/7 Ultimate Editions are also able to join domains, since they’re supposed to be everything-but-the-kitchen-sink editions).… [ Continue reading ]
After getting my PIX to boot in my previous post, I decided to run through the password recovery procedures.
When meeting with a potential customer the other day, she mentioned that she had a running PIX with an unknown password.
I thought I’d refresh my PIX skills and decided to bust out an old PIX 506E we had sitting in the office.… [ Continue reading ]
While staging a clustered Hyper-V environment this week, I ran into a head-scratching issue. After provisioning a few LUNs, masking them, and adding them as available storage to Failover Clustering, I began setting up the virtual machines on one of my cluster nodes.… [ Continue reading ]
This morning, I found myself in the unfortunate circumstance of the dreaded 0xc0190036 error. There is not a lot of information about this particular error code. It is, in fact, related to inaccessible or corrupt files.
During an update process, many files are flagged for replacement during the next system boot–that way, the system can keep running until the next convenient restart.… [ Continue reading ]
Recently, we renumbered a client’s network to reduce broadcast traffic and introduced two new redundant internet connections. Everything seemed fine in the initial testing, and we all went home.
The next day, when we were sifting through the fallout tickets, there was a recurring theme–Windows Mobile devices were no longer synchronizing.… [ Continue reading ]
A customer approached me with a some puzzling issues. They noticed a bunch of 1053 and 1054 Userenv errors in their event logs on their virtual machines. 1053 and 1054 error messages have very similar wording:
1053 – Windows cannot determine the user or computer name.… [ Continue reading ]
Blue screens are no fun. Trying to resolve them without the proper tools can be even less fun.
In my experience, a large percentage of blue screens are the result of some poorly-tested or incompatible third-party device drivers. For the desktop crowd, a round up of the usual suspects includes scanner, printer, and video drivers.… [ Continue reading ]
From time to time, I’ve found myself in a situation where I’ve needed to re-create MSDB. Unfortunately, most of the guides on how to do it give just basic overviews, leaving the unlucky admin muddling around.
Here is a real step-by-step for SQL Server 2005.… [ Continue reading ]
A few months ago, I ran into a problem when copying large files between two tiers of a network in one of our datacenters. I was doing a hardware upgrade on some Hyper-V hosts in a DMZ and was copying the images to a backup server while I swapped out hardware components in the Hyper-V hosts.… [ Continue reading ]
