I have had a similar experience to yours - although possibly not exactly the
same.
Some time ago, I issued a CASPOL command on a machine, and was then able to
(a) write VB 2005 code where the source code was on the network, and (b) run
the resulting .exe's from the network.

Then I lost both abilities.
I hadn't used that machine to do DotNet stuff for a couple of months - and
when I did try I found I had security problems in both areas.

A few days later, in Windows Explorer, I right-clicked a zip file on the
network, and got a message about "this page has an unspecified potential
security risk".

I looked that up on the web, and found a suggestion about changing an IE
setting.
In Internet Explorer,
- go to Internet Options / Security
- click on Local Intranet
- Click the Sites button
A window should pop up saying "automatically detect intranet?"
Turn OFF that "main" option, but leave the other three options checked.

A "help link" in that area of Internet Explorer appeared to confirm that
changing that setting was a good idea.

It seems to have fixed my problems.
