All gathering tasks for One or More Exchange Servers fail with Error: "the following error occure (90904)

All gathering tasks for One or More Exchange Servers fail with Error: "the following error occured during the processing of a given gathering: No such host is known"

This is caused if netbios name resolution fails to resolve the IP address of the Exchange Server using the netbios host name.

WorkAround 1:

1. Resolve Netbios name resolution issue within the environment
2. Confirm that the MessageStats server is able to ping the netbios name of each Exchange Server.
3. Rerun the MessageStats Gathering tasks and confirm they are successful

WorkAround 2:

1. On the MessageStats server add an entry for each Exchange Servers netbios name and IP in the local hosts file (C:\windows\system32\drivers\etc\hosts).
2. Confirm that the server can ping the netbios name of each server and that the correct IP address is now resolved.
3. Rerun the MessageStats gathering tasks and confirm they are now successful.
