Windows 7 VPN Client Does Not Connect, Error 2250

A laptop, which is a Windows 7, would toss this error 2250 after an excruciatingly slow process of trying to connect to a PPTP VPN server (WatchGuard). No other laptops or computers are having any issues connecting to the same VPN server. Everything regarding the process of connecting or even pulling up properties is met with a very sluggish performance. I ran a PRO version of Malwarebytes scan and it found only one infection, but while it was scanning the Microsoft Security Essentials discovered a bunch of viruses and cleaned them up. I suspect that this whole thing is due to some nasty virus cocktail that has inserted itself into the TCP/IP or the windows authentication protocol stack. It always fails after trying to verify the user name and password, which should get verified after "All devices connected" message is displayed. I tried switching from WiFi to the standard Ethernet cable connection, but to no avail. I also tried running the "netsh int ip reset resetlog.txt" to reset the TCP/IP stack at the admin command prompt, rebooted the machine and it still errors out. I restarted the client's AT&T DSL modem and it still did the same thing. I'm at the end of my wits on this one, except that I haven't tried the ComboFix yet. I can supply more logs later on this evening if anyone cares to respond to this message by then. Any suggestions?

Thank you!

One more thing I've tried is creating a brand new VPN connection to a completely different WatchGuard VPN server and the error is the same. The slow process that takes place while it's "dialing" the server is something I've never seen before. The computer in all other respects works fine and shows no signs of a bad performance hit whatsoever.

The attached text file contains the application event log entries relevant to this issue. The screenshots show the viruses that were quarantined and the DCOMCNFG application error when trying to click on the COM+ Applications folder.

The ComboFix took care of the VPN issue, but the DCOM catalog problem remains to be fixed. The two are probably unrelated. I would say I answered my own question and fixed it. Case closed.
