I want to manage iPrint on a new server with the iprntman-tool.

If I execute an iprntman-command in a Windows-Console, I have to enter
username and password, then I receive the following error:

Unable to process request: Bad Request

Additional informations:
- My System: OES SP1, full patched
- My used command for testing: iprntman psm -i -s <serverIP>
- At the serverconsole I can execute the command without error
- If I use the IP from a second server with OES 2 SP3 I don't receive
any error

Any ideas?
