The Unspecified Error I wrote about not long ago came back on my server. I thought that reinstalling ASP.Net would fix it once and for all but I was wrong. I installed a new antivirus product called NOD32 and ran a full scan. It found a few little cyber-squatters sitting on my machine and disabled them. They were:

Win32/HacDef trojan
Win32/VB.NEI worm
HTML/Amazofraud.N trojan

Hopefully, they were the problem. I just finished reinstalling ASP.Net again, so we'll see how it goes this time around.
