Redirector Error

We have 3 member servers. Server “A” is an application server which runs an old Fox Pro database software, Server “B” runs the client software with a script to process tasks at a scheduled time (Like an automated workstation), and Server “C” runs a realtime application that shows processed information from the automated workstation. Server “B” is the one that gets a error and it reads, “The Redirector has timed out a request to Server “A””. This happens about 4 to 5 times a day. I’m fresh out of Ideas..
