Strange error accessing Sharepoint

[country73]

A little background first...
I have been thrown in as our company's Sharepoint administrator (our previous administrator left the company a little over a month ago) and it has been a very long time since I have had to do anything with Sharepoint.
Everything has been going fine until this week. There doesn't seem to be any set pattern, but individuals have been getting "Error - Operation aborted" by just trying to access our site. One day they can access it, the next they can't. Two individuals that have been set up identical will have this issue. One can access with no problem, while the other gets that error message.
I really have no idea as to where to start with this, and I'm just starting to dig into the "Windows SharePoint Services - Inside Out" book to see if I can find something relatively similar to the issue I'm having.
I'm just hoping that someone may have some ideas so that I may trim my search down, or a solution to this problem.

Any help would be greatly appreciated!
Thanks,
Chris

Our sharepoint is setup with our main site and a disaster recovery site. Both sites are identical except for the address (of course) and backed up to one another. Everything that we have on our disaster recovery site is not accessible to everyone when our main site is up and running.
For some reason our Network Services group had both of the addresses up and running and so whoever picked up our Disaster Recovery address for Sharepoint would get the error message.
We shut down the address to our DR site and the problem was solved.
