I have two VM's of Server 2012 on Azure. From A I can access B via \\10.4.2.6\c$ without issue. Until yesterday I can access B from A via \\10.4.2.4\c$. I can still ping B from A and get a response. Disabling both firewalls doesn't help.
The error message I get immediately upon doing a Run command to \\10.4.2.4\c$ is Windows cannot access \\10.4.2.4\c$
. I read that there are some KB articles that talk about something like this, but I've installed everything from Windows Update and rebooted several times and I still have the same issue.
I should add that this is an image provided by MS as part of Azure. I haven't changed it at all since I was last using it. I connected to server B from server A, copied some files, and shut the VM down. This morning I turned it on and tried to copy some other files and couldn't. Further testing revealed that I can't connect to any share anywhere in the company and I used to have no issues. The error is always the same and always immediate.
I can not connect to any shares whatsoever on any system with in the network from that machine. I can connect to said shares from other machines on the same subnet. I can ping the machines I can't connect to with no issue. I was able to connect to several shares just the day before.
Browsing to \\10.4.2.4\ yields the same error. Network sharing is enabled; I disabled and re-enabled it to be sure. I shared C:\Temp on 10.4.2.4 and SoftPerfect Network Scanner sees 10.4.2.4, but no shares. I can RDP to 10.4.2.4 with no issue.
