Iprint Manager keeps crashing!!

Hello,

I posted the "iprint error" question below now that problem seems to be
killing my iprint manager as well. The iprint manager won't stay up for
more then a day at the most.

The errors i keep getting in the iprint manager logs are.

01/20/06 08:31:45, Operation Set:, Error: 506D000C - object not found, User Name: 255.0.0.1, Address: 255.0.0.1, Object Name: unknown

These just keep come about every two seconds. I have no idea what this
could be. I really don't want to waste a support call for something like
this.

Does anyone have any idea where to start troubleshooting this problem?

Thanks,
Matthew
