Print Server Drops User-Connections

By tppurdy ·
I have a print server running NT workstation, recently it has been dropping users from the network printers. I have replaced the NIC, increased the ram, and it is still happens. One message I receive is"RPC Server not available", this is @ the client machine. A reboot usually brings brings the printers back on-line. Other times the printers will disappear completely. Using HP JetAdmin don't find any errors there, except Server not found- but you can still do a test print to that particular printer.

Print Server Drops User-Connections

by NetTek In reply to Print Server Drops User-C ...

NT Workstation can work fine as a print server in small peer-to-peer environments, but I recommend you use NT Server if you have a LAN with more than 10 users. NT Workstation can only handle up to 10 concurrent user connections. If you are using it as a print server, it will start to drop clients connections during heavy printing times, and the clients will begin to receive the RPC error.

Very Good! I forgot about the 10 user limit. Thanks.

To further elaborate on what the previous person just wrote. NT Workstation only supports 10 user connections. That means you could install as many printers as you like, but only 10 users will remain connected to the print server because thats allthe connections workstation supports. I'm assuming that because of that, users 11+ are being disconnected from the resource until a connection is available. Hope that points you in some direction. TJ

The RPC error is probably not caused by excessive connections, but by excessive activity for the spooler itself.

Older versions of the spooler for NT are susceptible to RPC server freezes and other problems when overloaded. Get the latest versionof the spooler by applying (or reapplying) Service Pack 6a.

The above answers about NT Workstation accepting only 10 concurrent user sessions are correct, but you can share the printer among far more users from the same workstation if you simply lower the AutoDisconnect time (default is 15 minutes). Lower it to 1 minute.

This will provide a friendly disconnect from the print server 1 minute after each user completes their print job - thus freeing the server connection for the next user who tries to print. This solution allowed us to have 30 printer users connected to a LanMan server with a 10-user concurrent session limit.

Configure the AutoDisconnect time by running the following command from a command prompt (beware the word wrap):

net config server
/autodisconnect:time_before_autodisconnect

Specify the time in minutes.

Another idea for raising the maximum connections -

A registry hack that might work under NT Workstation is to add the following key:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\LanManServer \Parameters

Add a string value to this key named Users, and set its value to FF (hex).
