Hi,
I'm having the strangest problem with one of our windows servers. The windows filesharing just stopped working after several years of continues running.
I believe I have tried everything. I have restarted the server, disabled the firewall, removed the file and printer sharing and then reinstalled it. Checked and changed local policies. There is no 3rd party firewall or antivirus installed. I have checked the network traffic on the server and I can see the other server (that’s trying to mount a share on my "broken one") but no traffic is sent back. I can access a shared folder on my "broken server" locally by using \\127.0.0.1\share. The server is a virtual machine running on Hyper-V and I have tried to access it from VMs running on the same host without success. I have tried to access it using DNS name, NetBIOS name and IP, and they all work fine locally but non works from other servers.
The other way around works fine, I can mount other servers on this one.
