We're running NetWare 6.5 SP5. When some users try to install some
printers from iprint web portal, they get the following error message and
the installation process aborts.

Error message: The remote procedure call failed
Error group: Windows
Error code:1726

With this error the spooler stops. After I start the spooler again (net
start spooler)I can see the printer installed and functional.

How can I avoid this error.
