Hi, i've this trouble.... A customer has a Windows Server 2003 Standard Edition SP2 with the following problem: when it goes into start-> run-> \ \ servername i can view properly the list of shares but if i try to access to any of these shares i get the message "No network provider accepted the given network path ". If I do the test by going to Start-> Run> \ \ ipaddress of the server i'have directly the message "No network provider accepted the given network path" without even seeing the list of shares. I checked that DNS is working properly. I performed a nslookup, a dcdiag / test: RegisterInDNS / DnsDomain a dcdiag / test: connectivity, a dcdiag / test: dcpromo / DnsDomain: FQDN / NewTree / ForestRoot a netdiag / test: dsgetdc / d: DomainName / v and get all positive results. I also followed as shown in kb 841570, but does not solve anything. I am always with the problem reported. Someone can help me?! Please... Thank's in advance

Hi, Is the time in sync on the servers? It seems to me like some authentication problem.

here is an thought. Have you verified server is listening on SMB port 445? use the "netstat -an" command to verify that SMB protocol is enabled and server is listening on port 445 and 135

Hi, thanks a lot for your reply. I've check time sync and it's ok, and also all SMB protocol is enabled and server is listening on port 445 and 135 but i have the same error. any idea?

Hi, only updates that I have run on this server were Microsoft Updates (only security updates), any other patches or software was installed. On the server is running Symantec Endpoint Protection 11.0.6 but this is always running on this server also before this trouble. Anyway thank you very much for your help!

Hi, I suspect that the installed third party Antivirus software may cause this issue, could you try following the KB article below to remove or update it and check if this issue persist : Unable to access Shares "The specified network name is no longer available" when Symantec Endpoint Protection prior to 11.0.4202 (MR4-MP2) or Symantec Antivirus 10.2 are installed on a Windows 2003, 2008 or 2008 R2 Server http://support.microsoft.com/kb/961293 Thanks.
