>From the Exchange server, open two command prompt windows. In the
first window, ping one of the GCs by NetBIOS name. In the other
window, ping the same GC by IP address, as follows:

Window 1:
   ping -t 192.168.254.1 > pingGCbyIP.txt
Window 2:
   ping -t gc1 > pingGCbyName.txt

After an outage, check both output files. If the ping by Name fails
but the ping by IP address does not, then you have a DNS lookup
problem. If the ping by IP and ping by Name both fail at the same
time, then you have a connectivity issue.

For DNS issues:
   Make sure the Exchange server is configured to query ONLY internal
DNS servers, not public (ISP) DNS servers. The local DNS server
should be configured to forward any unresolvable requests to a public
DNS server.

For Connectivity issues:
   Start with the basics. Check the NIC, check the patch cable, check
the port on the switch, etc.

Hope some of this helps.
