We have an Iprint server setup with a bunch of printers. All has been
going well so far. All of a sudden, when I go to install a Printer for a
user through the Iprint Page I receive the following error.

Error Message: The Specified Username is Invalid
Error Group: Windows
Error Code: 2202

This happens for any printer (we have about 25 printers installed on
Iprint) I click on to install.

Any Ideas
