What is causing an application to work again after re-enabling the network?

Question

We are using a client/server versioning system (Perforce). Randomly, a client gets disconnected and is only able to reconnect when the user disables and re-enables the network card. The weird thing is that it happens with different users, hardware (including NIC chipsets) and moments of the day. The affected user can access to other servers on the same LAN and non-affected users are able to work with whatever they want, including Perforce, without any problem. What part of hardware/software I would most likely blame for that?

Thanks.

Answer 1

This sounds most like a problem with the Perforce server.

I would check its NIC and maybe try to disable Large Send Offload and/or Checksum Offloading, if they apply.
