Exchange Cluster Plugin dies Constantly when trying to expand it in the Backup window due to wron (81431)

Date: Jan-2011
Product & Version: NVBU any
OS Version: Any
Module & Version: Exchange plugin
Application version: Any


Symptoms:
When trying to open the plugin to see the storage groups, there is a popup that says that the plugin died unexpectedly.

Also, Backup jobs uing the same plugin (that were set up previously while the plugin might have been working) fail with the same error message: "plugin died unexpectedly".

The best and fastest way to generate a trace file for this issue would be to enable the generation of the trace file on the client with the plugin and try to browse the plugin until it dies.

In the trace file, if the issue is the configuration of the domain, you will see the following in the nvexchange_browse_xxx.log file:

...
0 EXCHUTIL:6992 1065 0 153951 valid ip address '172.16.1.220'
0 EXCHUTIL:6992 1066 0 153951 full hostname is 'exchserv.domain.com'
0 EXCHUTIL:6992 1052 0 153951 'SRVMSG' Virtual Client is mapped to 'exchserc' Exchange Cluster (Virtual IP(or hostname):172.16.1.220).
...
1 EXCHUTIL:6992 700 0 153958 Method CreateExchangeConfig: starts
1 EXCHUTIL:6992 935 1 153958 CreateExchangeConfig: server = 'exchserv'
1 EXCHUTIL:6992 936 1 153958 CreateExchangeConfig: account = 'administrator'
1 EXCHUTIL:6992 937 1 153958 CreateExchangeConfig: password = 'u7:%<CC?<'
1 EXCHUTIL:6992 938 1 153958 CreateExchangeConfig: domain = 'wrongDomain'
...

As it shows, the domain name in the second part is different from the domain name in the first part of the tracefile.

Another way to make sure is to do a reverse nslookup on the ip address of the virtual Exchange Server which will show the full name with domain.

Changing the plugin configuration to the 'real' domain name (from wrongDomain to domain.com) results in the plugin to be browsable again and the jobs being successful.
