I have a network attached drive, plugged into my router. Im connecting to the router from the client pc using WIFI. I'm using Windows 7 -

I can see the drive using it's IP address: However, if i try to use it's name - "nasunit" then windows displays the "cannot access \\nasunit" box....

It used to work (up until an hour or so ago)

I haven't changed anything that i can remember....

Has anyone got any ideas as to how i can fix this? I could add an entry to the hosts file, however, i shouldn't need to do that....

This question came from our site for system and network administrators.

Ping NASUNIT to verify that your PC sees the correct IP address for that resource. If it doesn't, do an IPCONFIG /ALL to verify that your DNS servers are correct. You can also do an NSLOOKUP on the name to make sure that you're getting the correct IP information from those DNS servers.

how would one know that your DNS servers are correct? What would you expect to see from an nslookup, and how would you know if it's improperly configured? – MedicineMan Sep 18 '10 at 19:45
1. It all depends on how things are configured within your router. The DNS servers on your PC could point to your router's IP address (which will, in turn, use your ISP's DNS servers) OR it could use the public DNS servers provided by your ISP. – Mark Sep 20 '10 at 11:50

I checked the settings on my router... i enabled "NetBIOS announcement" and set "NetBIOS node type" to Mixed Mode and it seems to work.... not sure why...?

Do you have a DNS server running on your network? Can you ping your router by name? What does nslookup return? What does ipconfig /all show as your DNS servers?

This should go on

That said, the first thing I'd try is power-cycling the router, then if that doesn't work powercycle the drive.

Go to the windows command prompt. (Start-cmd).

Type ipconfig /flushdns

Type ipconfig /registerdns

See if that fixes your problem.
