I came home last Thursday hopefully finish my little WebService project,
while i opened my project there it was - an error, something about cannot open web pages.
I've tried to open my Consumer Web Application project - same error occurred.
The really strange behavior was while trying to open my COM+  clicking on "my computer" tree node that cause in strange closing window?! no error written.

While surfing the net - i found explanation about how to fix the problem- which include full exhausting description about how to re-install your component services.
so continue goolge up some of my event log errors, and finally I found something that would be good try before starting the component services re-installation.

run those command lines:
regsvr32 oleaut.dll
regsvr32 ole32.dll
afterward, I've tried to enter the COM+ again and it works just fine.
And even my projects are running great (even my undocumented bugs disappear).

I hope it will be helpful for you too, it is worthwhile to attempt this before re-installing the COM+.

A little bit about ICQ - I always have strange problems when my bro install/upgrade versions,
I tell you don't mess with those people.
