UNC Error 64 “The specified network name is no longer available”
Posted on 2005-04-07
Alright..here we go......
I have 3 servers (Windows Server 2000) that do voice recordings real time. At the time of the recording, it is streamed to a network share for storage. Just before the recording is going to happen, my service checks the UNC pathname for the existence of the share. On occasion I receive back an Error 64 “The specified network name is no longer available”.
However (there always is one), this is happening on one machine while the other two are working and writing fine.
- The setting on the share are set at full control for the windows service account that does the writing to the share.
- THe share is set for Maximum Number of Connections
- The connection between the two machine is tcp/ip 100mb full (auto negotiate at both the switch and the nic), going through a Cisco 2950G switch. I have nothing as far as collision or errors on the switch in 9 months of constant uptime.
- I have no errors logged in Windows Event Viewer. The OS is returing this error to my service AND a third party application I have running.
Please help!! I have read (I think) every article relating to UNC, SMB, MTU packet fragmentation and have found no really solid wording on what the problem may be. Thanks in advance!
