<div>
Do you have the same issue using the ip address?
</div>


<div>
Yes. &nbsp;My other file server works fine.
</div>


<div>
1. reset DNS <br />
2. run ipconfig /flushdns from a command prompt<br />
3. does the server name resolve using nslookup
</div>


<div>
nslookup did not work. &nbsp;Tested with my other servers and it resolved except with problem server.
</div>


<div>
If I ping server my name it does work though.
</div>


<div>
DNS issue, check DNS and see if there is a duplicate A record. <br />
<br />
Did you do ipconfig /flushdns on the server having a problem.<br />
<br />
Check the NIC make sure there's not a wrong entry.
</div>


<div>
No duplicate A record. &nbsp;Flushed dns and checked NIC and all settings are fine.<br />
<br />
Now I am able to do nslookup but still get that error when opening drive.
</div>


<div>
disconnect the mapped drive and reconnect
</div>


<div>
This is how I was able to fix issue.
