    Well I take it your exchange server still has network conectivity ?

    If so check all your active directory servers are up and are able to be conencted

    If so find which are your Global Catalog servers :

    Make sure they are all up and runnign correctly.

    Hope thats some sort of help !

      The error means what it says. One or more of the global catalogs are not responding to Exchange. As for the cause, there could be numerous. Without knowing your network topology I wouldn't know where to begin with suggestions on where to look.

        Download and install the Exchange Troubleshooting Assistant on the Exchange server and run it and select the "Performance Troubleshooter" and then the "Exchange processes are failing" tasks and see what they report.

          you could also utilize "dcdiag" with the switches to check all DCs and GCs.

          C:> dcdiag /s:<DomainController> /v /a (to check specific dc's)

          if the test isnt run from a DC, you will need to specify the srvs name.
