We have a server that is critical for our operations just upgraded from NT 4.0 SP5 to 2K SP4. After this upgrade, one of our internal data transfer processes, which runs on a NT 4.0 SP5 server, keeps having trouble reading files from the upgraded 2K SP4 server. The files being read are shared via a mapped logical network drive. The process is continuous and is supposed to keep the connections between both servers very active at all times.
We discovered that connections to the 2K SP4 server made from other clients are reporting the error "An error occurred while reconnecting (network drive letter) to \\(Our server IP address)\(path). The local device name is already in use."
We already looked for answers at Microsoft site and the recommendation is "install SP1"... yeah, right.
Also, we looked for answers at this site (Experts Exchange) and found some recommendations that have been already applied: syncronizing the time of both servers, including the servers in the same domain, and tried to configure the security settings, but the instructions in the message were confusing / brief, and we couldn't find the correct place where to check it.
Besides, we discarded activating TCP/IP KeepAlive, as the process between the servers is keeping VERY alive the connection. We have monitored the status of the logical drive from other client, by pressing F5 continuously and the icon keeps changing from "X-ed" to "not-X-ed" as if the connection continuously would be broken and restablished.
What else do you guys recommend we could do???
