What is the supported number of remote PXE Servers that can be managed by a single PXE Manager in Ghost Solution Suite 3.x?
GSS 3.x
The PXE Manager is capable of managing up to 15 remote PXE servers. If the number of remote PXE servers increases beyond this limit, the likelihood of failure will increase regardless of the PXE Manager's configuration.
Another option would be to us the iPXE feature as it has been available since the Ghost Solution Suite 3.3 release.
