I have had the following error on 3-5 different users, and it is just randomly appearing. I am lost as what to do, and have sunken to the level of reinstalling windows.

While trying to print an email from GroupWise today I get the error: Function address 0x7153758 caused a protection fault. (exception code 0xc0000005) Some or all property page(s) may not be displayed.

I click the OK button at the bottom of that box and get another message: Function address 0x715d8f6 caused a protection fault. (exception code 0xc0000005) Some or all property page(s) may not be displayed.

After clicking OK on that box I get a dialog box stating: Before you can print, you need to install a printer. To do this, either double-click the Add Printer icon or click the Find Printer...button located on the General tab of this dialog. The Print box opens showing the default printer BWPRINTER.SECPOOL.ESC18 to be the selected printer. However, it still will not print.

This happens both in Groupwise and IE6 while trying to print.

I have done some troubleshooting, and this is what I found.
Reinstalling iPrint client and printers does nothing.
Reinstalling IE6 does not work.
Reinstalling Groupwise does not work.
Groupwise and IE6 will print to local printers if they are set to default.
