Homegroup password incorrect

I've got 4 pc's all installed with W7 RTM, 3 pc's are 64bit and 1 pc has got the 32bit installed.

My problem is two of my 4 pc's (64bit) can join the homegroup, but the other 2 gives me a error of: incorrect password.

What I've tried
1. Ive read all you forums regarding this error and tried most solutions.
2. Tried to delete homegroup on all pc's and reinstate it
3. Deleted files in die the following folder: C:\Windows\ServiceProfiles\LocalService\AppData\Roaming\PeerNetworking
4. Tried various different passwords.
5. Taken off my passwords on the user accounts
6. Created different users without passwords
7. Tried to make the 2pc's that cant connect to the homegroup the host, but then none of the pc's can join the homegroup, also password incorrect.
8. I checked my firewall settings, they the same on all 4 pc's.
9. The pc's that cant connect can ping the host and other pc.
10. I can ping both ip and computer name
11. Disabled and enabled IPv6.

I hope you got some additional stuff I can try.

Try synchronising the time on all of them. Even if it's 1/2 second out, it still won't connect :)

NNOOOOOO, you not gonna believe me this actualy worked. Thanks a lot for the trouble.

At first after I synchronized the times homegrouping did not work, then I shutdown all 4 pc's and started them up individually from the host pc and then it worked.

Thanks again.

Your welcome Oortjies :)

Rsvr85 nice post a new idea we can all use.

Ken

how can i sync the time on my pc's? i am having the same problem but dont know how to sync the times...

WOW... thanks a lot!! I spend hours and this was the solution. I forgot I change the time in one PC... now it works perfectly... thank you!!

I don't know if it helped, but after trying the time change on my 3 pcs, which didn't work, I went to my desktop and deleted the current homegroup that I was trying to setup. After that, and syncing the times again, I restarted and setup a new homegroup (with new password) on my desktop and was successful connecting on both my laptop and mini-notebook, first try.
