Failed to connect. IP address not found

[JMPY]

I have a VM Windows 2003 SP2 and I create a Backup Job with VSS and an account from domain Active Directory that is member from Domain Admins.

All others VM are backup with a Success state and It's the only one that are with the Warning state:
Failed to connect. IP address not found
I doesn't Quiesce with the VMware Tools and It's a SAN VCB Proxy backup.

The detail of the Help|Support information is:
