Recovery Solution - Reliable Network Services ARE Important.

While recently working a Recovery Solution issue, we encountered some problems.  The clients could not register and SSM jobs were not completing.  Upon reviewing the Event Viewer logs, we saw a consistent sequence of errors

 Altiris Recovery Solution Error Server Space Management 35 N/A SERVER "RemovePhysicalFile RemovePhysical() returned an error.

Altiris Recovery Solution Error Server Space Management 73 N/A SERVER "Error retentioning file 'winlogon.log' of user 'XXXXXXXXX' on volume 'C:'.
FileKey 10448642, file revision 13.

Altiris Recovery Solution Error Server Space Management 2 N/A SERVER "There was an error when a file was being processed for Recovery Solution Server space management.
Problem backing up the file.
File 10448642

Altiris Recovery Solution Error File Repository Engine 12 N/A SERVER "Unable to read file data from the Recovery Solution Server.

Altiris Recovery Solution Error Client Files I/O Engine 72 N/A SERVER "Unable to read data from reference file during restore.

Altiris Recovery Solution Error Client Files I/O Engine 69 N/A SERVER "Missing revision information during file and folder restore.

Traditionally, this sequence of errors has alway indicated the need to perform an upgrade on the Recovery Server.  After this step was taken, the problems still persisted.  A little further investigation showed that DNS resolution was not working correctly for the Recovery Server in question.  Changing the cluster configuration to require only a NETBIOS name, rather than the Fully Quilified Domain Name (FQDN) temporarily resolved the problem.  Substituting an IP address can work as well.

Having DNS  and network name resolution working correctly is always important - no matter which of the endpoint management products you use!
