Basically, i had search google for this but fail to get answer. Not sure is it common or wat.
OK, here is my case for IPC$ prompt.
I had a win2008R2 with a user name "A" with password "123" which also assign into Users group. I create a folder and share in network and put in "A" giving full access as well.
I had 2 winXP, which is XP1, XP2..
when i access using XP1 to open the win2008R2, it work fine with the user "A" and password "123". The account name and password is the local account for XP1.
when i access win2008R2 using XP2 which also the using "A" and "123", it prompt me "please enter password \win2998R2\IPC$". i try to key in "123" but it said password wrong.
This happen same to win98 computer as well.
thing i had done
1) enable guess account, not working
2) disable firewall, not working
3) change password for all local account, not working
4) edit the regedit for "local security policies">"local policy" >security option>network access : sharing and access for local account = classic local user authenticate as themselve", not working
