I'm sure that my IP is unique. I'm using an existing ethernet switch (one that have already serve well for my network). We have few connected PCs with different OS (some of them use Windows 7) and they are working well, except for mine.

why disable IPv6?
see article:
Windows 7 Homegroup IPv6 connection issues
pay special attention to
'2. Verify relevant services'
Workgroup is similar--have you joined workgroup? can you access internet?
All the required services are running without any problems.
Well, I disabled IPv6 because we don't use it. We have some computers with older version of Windows (Windows XP) and some variants of UNIX in our workgroup which don't support IPv6.
Also, I've set the appropriate workgroup from the start and have tried to restore it to default value and change it back, no result.
Unfortunately, we don't have any connections to internet (it's just a simple workgroup for us to share files among us) so I can't test whether I can connect to internet or not.
Any suggestion?
