When there is a network on computers that must "talk" & even 1 computer has a problem IT will cause issues with any of the other computers.

You need to find who on the network has the problem.

Testing the HI/LOW voltage signals is the only way to locate the issue.

The first thing I would try is using the remote to lower and raise the windows. Just hold lock or unlock button while pointing the remote directly at the drivers exterior door handle for a few seconds after the lock cycles. If no go from there try rebooting the computers......disconnect the battery cable for a few minutes, then reconnect and see what happens. If nothing...Then let the troubling shooting begin.
