I have six windows 2003 servers (R2) with SP2 installed in a workgroup at 6 different sites (inc. separate subnets). On one server in particular, I am receiving sporadic connectivity when attempting to access shares by IP address and receive the following error:
\\IP Address is not accessible. You might not have permission to this network resource".
Once I clear the errors and attempt to access it again, the share opens instantly without issue.
We are not using DNS for resolution. I have restarted the TCPIP NETBIOS HELPER and WORKSTATION services and the issue persists.
I am running continuous pings and there aren't any packets dropping.
