I have a home network with XP Pro and Vista Home. It was working perfectly on Friday and today (Tuesday) it won't let me access the XP machine. I keep getting the message 'Windows cannot access (computer\dir)' The details section: Error code: 0x80070005 Access is Denied. I haven't changed anything on either machine. There are several users and the PC's have user accounts with passwords and different access levels to different folders. I am set up as an administrator with full rights to everything on both the PC's. Both machines have all their updates installed including SP3 on the XP machine. Both systems are set up with static IP addresses. The XP machine has no problems accessing the Vista machine. I was able to run a backup from the Vista PC of files on the XP machine but I have a credentials set in the backup program. Unfortunately it isn't possible to set a windows logon credential in Vista Home. I have tried everything I can think of over the past 5 hours including shutting off the firewall in XP and changing the folder sharing access to Everyone. HELP!! Anything anyone can come up with would be much appreciated. I thought perhaps I could get XP to ask for a username and password but I can't seem to find anything on that either. Thanks in advance.1 person needs an answerI do too

If you use 3rd party Firewall On, Vista/XP Native Firewall should be Off, and the active Firewall has to adjusted to your Network IP numbers on what is some time called the Trusted Zone (consult your 3rd Party Firewall instructionsGeneral example, http://www.ezlan.net/faq.html#trustedPlease Note that some 3rd party Software Firewalls keep blocking aspects of Local Traffic even it they are turned Off (disabled).
