We have a new domain with two 2012 R2 GC servers. We moved a 2003 server from the old domain to this new domain. The 2003 server has a share that is mapped via group policy. At times, (no pattern discovered although it is usually noticed in the AM), some users will lose connectivity to this mapped drive. A logoff/logon or a restart will reconnect the drive. All power save settings are turned off. Anyone else experience this?
