Windows 2003 Member Server on Dell PowerEdge R410 with Dell SAS 6/iR Integrated Controller with 2ea Hard Drives RAID-1:
UNC shares are only good for about 15 Minutes after reboot then fail on only this one 2003 critical Member Server in the Domain. Only network shares are affected on this Server.
UNC Resolution Fails by Name and IP at same time to user and admin shares and cause major disruption waiting for file transfers and/or share access. Eventually, it errors out with can't access path.
The only thing I see out of sorts is that the WINS Server IP in the Static IP NIC setting do not resolve by name or respond to ping.
Our vendor application on this server is running a critical application and has been crippled by the failure of the UNC shares. The customer IT support resources have not been able to diagnose the problem after three LONG days of troubleshooting.
Dell OpenManage and DSET (Dell System Extraction Tool) appear to show everything is clean except for an Error 22 on Broadcom NIC which I'm trying to research further, but I surmise it is because the 2nd NIC is disabled.
We've Flushed DNS and verified the domain name resolves to a good DC / IP.
It seems like a hardware issue, but Dell diagnostics look OK.
Thanks in advance for your help.
