Multiple connections to a server or shared resource by the same user, using more than one user name, are not allowed.

Question

Windows appears with "\ipaddress\shared 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.

Multiple connections to a server or shard resource by the same user, using more than one user name, are not allowed. Disconnect all previous connections to the server or shared resource and try again."

Apparently, first message has nothing to do with the problem.

I would want to disconnect all previous connections.

Tried the basics
DISM .exe /Online /Cleanup-image /Restorehealth
sfc /scanow
net use * /d

Answer 1

DISM .exe /Online /Cleanup-image /Restorehealth
sfc /scanow
net use * /d

If you're running dism and sfc, you would have needed to launch cmd.exe with "run as administrator". That elevated cmd.exe will not see drives mapped from non-elevated processes unless you added the registry key for EnableLinkedConnections.

Try running cmd.exe without "run as administrator" and then try "net use * /delete".

When you access the server, do you always initiate the session the same way? That is, do you always map a drive letter, either from a "net use" command or the Explorer? Does "net use" show that drive before you try to map a drive with the second account?

What about granting access to your desktop login account to access all file shares so that you don't need to use a second account?

Ran net use * /delete. Found the first mapped drive and wanted to remove that. (Continuing will cancel the connections. Do you want to continue this operation? (Y/N) Y). Selected enter to delete the first mapped drive and not the one this post is about.

“When you access the server, do you always initiate the session the same way? That is, do you always map a drive letter, either from a "net use" command or the Explorer? Does "net use" show that drive before you try to map a drive with the second account?”

Have tried both “net use” and Explorer. Net use now shows no connections. (There are no entries in the list.)

“What about granting access to your desktop login account to access all file shares so that you don't need to use a second account?”

Because this is a shared drive for multiple users.

I will next go in using the mapping that gave me the message using Explorer and then the original mapped drive and no errors on computer 1. On computer 2 reversed mapping and there was no problem .
Looks like running command prompt without the administrator with command "net use * /delete" worked even though there was no evidence the problem mapping was present.

Answer 3

In DNS check that the (A) record name correlates to the IP and check that the PTR record IP match the host name

From a machine that can map the drive perform an NSLOOKUP on the IP and hostname then perform the same action on the one that does not work. If you have more than one DNS server look at the DNS server that is being used in the NSLOOKUP command. Check your network adapter settings where DNS Server is configured to make sure it is the same between both machines.
