Vista VPN Connection Problem

We found the solution to why our Vista 64bit SP1 systems were having trouble establishing a VPN connection. It was due to something in the DNSAPI.dll. We disabled the DNS Client service on the systems and they are able to connect just fine.

Since the Windows Event logs were reporting:

“Faulting application svchost.exe_Dnscache, version 6.0.6001.18000, time stamp 0x47919291, faulting module DNSAPI.dll, version 6.0.6001.18000, time stamp 0x4791ace0, exception code 0xc0000005, fault offset 0x000000000000d64a, process id 0xac8, application start time”

I’m thinking the problem lies with a bad .dll in SP1

Vista and VPN Connection

I haven't posted in a while due to having to work on a VPN connection issue with Vista clients. Basically, when the user attempts to connect to our VPN server the connection is dropped with error code 800.

It looks to be a problem with Netbios over TCP in the network connections themselves. I'm still researching the issue. So far I have reloaded my test laptops well over half a dozen times trying to rule out network card drivers, user permissions, and OS service packs.

XP SP3 Installed

WSUS pushed out XP SP3 to user systems just fine. Today I'm having trouble with a MacBook that is setup with XP and OS X. When attempting to install SP3 on the XP side I'm getting an error message about not enough room on the C drive.

Postponed Updates

Came in this morning and found that the hub to the test systems was unplugged. My assistant needed the cable for another system. Plugged the systems back in and will check tomorrow morning.

XP SP3 via WSUS

XP SP3 was dropped to WSUS last week. Pushed it out to a few test systems yesterday via WSUS. Waiting to see what happens tonight when the updates from May get pushed out to the systems. If they install without errors I will push it out to the rest of my XP systems later this weekend.

Updates Fail After XP SP3 Installation

While bringing up a XP system to image, I ran into a weird issue with SP3.

Like a good admin, after bringing up the system I went to the Windows Update site. Low and behold SP3 was there waiting for me. I installed it and everything seemed fine till I tried installing additional updates, which all failed.

I tried the solutions in this link but none of them worked so I reinstalled the system. Hopefully, Microsoft will correct this issue before it gets pushed out to WSUS.
