256986 Description of the Microsoft Windows Registry
WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk. Error 3013, "The redirector has timed out to SERVERNAME" usually meansthat the Server that you are attempting to connect to is:
Either busy and cannot respond before the rdr timeout
The network could be busy
Bottleneck in the network
As to troubleshooting this problem, you may want to exhaust all meansbefore deciding to increase the amount of time before the redirector stops (SESSTIMEOUT). The SESSTIMEOUT parm can be set in the following registry location:
Some things you can try are to obtain a trace of the packets onthe network. You want to zoom in on the amount of time it takes for theServer to respond back to the workstation.
Another idea is to perform what ever operations that was done backwards.If you were connecting to ServerA from ServerB, try connecting to ServerBfrom ServerA. Also have another client attempt to connect to the sameserver to see if both redirectors have the same problem connecting to thesame server.
You may also want to check the following items:
Check to see that the latest network driver is installed.
Check to determine whether the network adapter has a configuration utility that allows tuning parameters. If so, try maximizing the network performance.
Valid values for the SessTimeout registry key are:
Microsoft Windows NT Advanced Server 3.1, Microsoft Windows NT Workstation 3.1, Microsoft Windows NT Advanced Server 3.1, Microsoft Windows NT Workstation 3.5, Microsoft Windows NT Workstation 3.51, Microsoft Windows NT Workstation 4.0 Developer Edition, Microsoft Windows NT Server 3.5, Microsoft Windows NT Server 3.51, Microsoft Windows NT Server 4.0 Standard Edition
