In English Jerry ... in English???? Is this what you are talking about??
Procedure:
1. Edit the registry observing usual caution.
2. Locate the key HKEY_CURRENT_USER\Printers\DevModePerUser
3. Remove all VALUES for Network printers of the form:
\<print_server_name ><printer_queue_name>
4. Locate the key HKEY_CURRENT_USER\Printers\DevModes2
5. Remove all VALUES for Network printers of the form:
\<print_server_name><printer_queue_name>
Also, the issues described in
http://www.24help.info/t310486-samba-xp-bug-client-spooler-loop-ms-kb-329234.html
seem to still me lurking around. As you put it,
"Some old bugs never die I guess.
cheers, jerry"
This one still has some life left in it... The KB article describes the
following:
"When a client opens several network printers that are all on a *single*
server and then selects printer properties and preferences on *all these
printers at the same time*, the spooler on the client side may not respond
as expected. Additionally, the CPU-utilization of the print server may
increase and remain high. In this scenario, a network capture shows that the
client repeatedly queries the print server for printer properties.
A network capture displays the following remote procedure call (RPC) request
from the client:
MSRPC: c/o RPC Request: call 0x3845 opnum 0x8 context 0x0 hint 0x734"
In our case now, the new xp service packs have been installed that were
designed to remedy this. I dunno, something is still nuts. I get thousands
of packets generated trying to access the printers. It seems to be some kind
of loop. Here are the ethereal summary packet lines for 50 packets. Notice
the SMB-DCERPC-TCP-TCP-TCP loop:
