Hi.

I'm trying to access our Sharepoint site from file explorer. But everytime I do that, I get this message:

"You were not connected because a duplicate name exists on the network"

 Message
I've checked our DNS server and there are no duplicate names and when I ping the computername, I get the right IP.

I've have no problem accessing our Sharepoint site from IE.

What can I do to solve this?

Hi Marine.

I forgot to mention that we haven't got any problems accessing the Sharepoint server UNC from other servers or client-computers. It's only this server.

This solved our problem:

Solution:
On our Sharepoint server, we created this DWORD:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\LanmanServer\Parameters
Create a new DWORD with the following details:
Value name: DisableStrictNameChecking
Data type: REG_DWORD
Radix: Decimal
Value: 1
Then reboot the Host.

After we solved this problem, we got this error:

 Windows cannot access Windows cannot access
We solved this one by installing Desktop Experience on the server.
