Vista/IE opening with no connection

For a while now I have had issues opening Internet Explorer on my work computer. The program would be opened, fail to get a connection and I would shut it down and repeat until it did connect. The home page was aimed towards a local Intranet address but this wasn't the issue - whatever the home page was set as, the same problem occurred.

Now this may have started once Microsoft ISA Server became the network's way out to the Internet as I am sure it didn't happen before. However I can't pinpoint it for definite.

As I mainly use Firefox for development of web sites at the moment I haven't really been too bothered about it. It was just an annoyance that I had to try starting IE several times before I had a successful connection.

At random intervals I did try and look into it through our trusty friend Google but to no avail.

Recently however, I found out it was happening on other computers on the network also and users were just putting up with it rather than informing me.

Anyway, I had another Google session on this last week and found this post about tabs not connecting. Now I didn't do everything mentioned on this page but simply decided to try the following in the command prompt;

regsvr32.exe /n /i ieframe.dll

Once I had done this, my IE then seemed to connect every time I started it the first time so I am hoping I have solved it.

I passed the same info onto some colleagues and one says it is now better but not perfect. I'm yet to follow it up to see if it is the same problem.

As far as I am concerned though, so far so good!
