Having an issue with one of our Win2k8 R2 file servers. Trying to access C$ or the Admin share is giving us an error (see error details that the bottom), however we are able to connect using the server's IP and FQDN.
- can access
\\172.16.x.x\c$
with domain cred - can access
\\server.domain.local\c$
with domain creds - cannot access
\\servername\c$
with same domain creds
Server pings fine with Hostname, IP, FQDN, the Primary DNS suffix is also correct.
DNS, PTR and Wins records are all correct for the Server
I have checked that I am not trying to connect with cached credentials in the Windows vault, the server is also appending primary and connection specific DNS suffixes to the hostname.
Any ideas what might be causing this issue?
Error Details:
c$ is not accessible. You might not have permission to use this network resource. Contact the administrator of this server to find out if you have access permissions
update
@ChrisMcKeown comment was the solution I was looking for.
Seems that because I was trying to access C$ on a file server that I had already mapped shared to my computer using just its Hostname, e.g. z: \serverhostname\companyshare
It would not allow me to connect when explicitly supplying domain credentials to the C$ and Admin$ shares.
Not 100% sure why this is the case, but seems that it sees the IP, Hostname and FQDN as separate entities, if anyone can clear that part up it would be great.
NET USE
and see if you already have a connection to that server using just its hostname - if you do then it won't allow you to create another connection to the same server with different credentials - although as you have found, you can use the FQDN or the IP instead to create a new connection.
