Hi sukhigrwl
This appears to be a TCP/IP timeout.
Please apply the following settings on the Exchange nodes as well as NetWorker server:
1.- Group Inactivity Timeout is set to "0" in the Exchange client configuration in NMC.
2.- Add the TCP/IP settings on regirtry (DWORD Decimal values):
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\TcpWindowSize=256000
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\GlobalMaxTcpWindowSize=16777216
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\KeepAliveInterval=1000
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\KeepAliveTime=600000
On Solaris:
#ndd -get /dev/tcp tcp_keepalive_interval
7200000
#ndd -set /dev/tcp tcp_keepalive_interval 3360000
TCP settings on Windows 2008 R2:
netsh int tcp set global chimney=disabled
netsh interface tcp set global dca=enabled
netsh interface tcp set global netdma=enabled
netsh interface tcp set global autotuninglevel=highlyrestricted
netsh interface tcp set global congestionprovider=ctcp
netsh interface tcp set global ecncapability=disabled
netsh int tcp set global rss=disabled
I would recommend to reboot after these settings are applied.
Thank you,
Carlos

Good Morning Carlos:
thanks for your reply but i am able to help this issue yesterday with help of EMC Support (Julian Paul) and issue was one its have mount folder pointing to unknown drive which not exist in exchange server or somehow got deleted.
Second Service account used for net worker missing two Active Directory group named
Organization Management
Exchange Servers
so fixing all above solved my issue and once again exchange backups flying smoothly
best Regards
