How To Ask Questions The Smart Way

Before asking a technical question do the following:

Try to find an answer by searching the forum.
Try to find an answer by searching the Web.
Try to find an answer by reading the manual.
Try to find an answer by reading a FAQ.

Be precise and informative about your problem

Describe the symptoms of your problem or bug carefully and clearly.

Describe the environment in which it occurs (machine, OS, application, whatever). Provide your vendor's distribution and release level (e.g.: Windows XP SP1, Ubuntu 12.04 32bit, etc.).

Describe the research you did to try and understand the problem before you asked the question.
Describe the diagnostic steps you took to try and pin down the problem yourself before you asked the question.
Describe any possibly relevant recent changes in your computer or software configuration.
If at all possible, provide a way to reproduce the problem in a controlled environment.
 
This could be anything form the other PC not being turned on to it being on a different network, typing in the wrong name, etc...

Need exact details as to what you are doing and the network setup between the computers, operating systems versions on both systems, did this work before.

Don't know if you still have the issue, I recently started having this issue (seemingly out of no-where); just thought I'd post my fix. I have SuperAntiSpyware on my computer (I'm not advertising for them, just don't want anyone to go through all the long hours I went through), there's a tool in the "Repairs" section of SAS called "Repair broken Network Connection (Winsock LSP Chain)". As the program states, please use with caution. Once I ran that, I had to restart as it did something in the registry. Once it came back up, BAM, fixed; after about a month of trying to fix it... BTW, it says it's only for Window Xp (the tool), but I used it on my Windows 7 Ultimate 64-bit, no issues. Hope this helps :)
