We have an Access application that consists of a frontend MDE, with multiple backend MDBs, and distribute it in both 97 and 2K formats. I have one user (97 version) who consistently gets the message "Unable to impersonate DCOM client" when she tries to add any new records whatsoever, as well as in a few seemingly random times (my users are remote, so there is no way for me to do local troubleshooting). I don't have this problem with any of my other users.

I was wondering if anyone else has had this problem, or knows a bit about the error so I can find a good place to start working on a fix?

Thanks!
