Novell GroupWise Error Code C045
2007-05-02 by Thomas LottererI fought a battle with Novell GroupWise 7.01 Client on WinXP, causing error code C045 for no obvious reason. Multiple times a day. For months. Mostly without noticeable effect, sometimes with client lockup after pressing OK. Finally, a hint from Jürgen Dischner helped me resolving the issue.
The problem is caused by a defective display setting. Remedy: right click on the home folder, select properties, go to the display tab, notice your custom settings are selected, delete them. I did it two weeks ago and trouble has vanished.

Hi,
I ran into this problem, and fixed it by replacing the ngwguard.dc file in the archive-folder with one from another archive folder of some other user. After that the error did not come back again. I just wanted to post this somewhere, so people can find this solution which I had a hard time finding.
