Installing Data Protection Manager 2007 on a Dell NX3000
Dell has this great NAS device that runs Windows 2008 Storage Server Standard–the NX3000. The only problem is that Dell treats it like an “appliance,” meaning you can’t partition it the way you want. I recently ordered two with 6x1TB drives and wanted to deploy DPM to them.… [ Continue reading ]
Troubleshooting 0xc0190036 Errors on Windows Vista / Windows 2008
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 ]
Setting up a Receive Connect for Postini Re-Injection
For any of you that use Postini for email services, setting up reinjection for the receive connectors in Exchange 2007 is a lot more work than allowing connection and relay through a vSMTP server in Exchange 2003.

Active Sync Error 85010014 OTA with Exchange 2003
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.

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:
