Solution

This issue is often caused by an incorrect DNS entry for the client computer on the DNS server. Sometimes it happens after computer is assigned a static IP address and DNS server still have a record for the old IP. Try accessing computer using its IP address. e.g. \\192.168.1.105\c$. If this works update computer’s DNS record on your DNS server. Ensure that DNS server is functioning properly.
