I have had this problem with XP and now it is going on with Vista.
MY home network consist of 2 computers in a workgroup. Basic file and
printer sharing. 1 computer is XP Pro and other computer is now Vista
upgraded from XP Pro. Trying to do simple file and print sharing. Vista can
see and access XP machine but XP machine can see but not access Vista
machine. Says the generic message of access denied, password, etc... Neither
machine has a password and both have same account name for login. I use to
be able to do the sharing when both machines were xp and one day it stopped.
No reason or changes made on my part. I thouht after I upgrade to Vista on
the machine the problem may fix itself but it just carried over. I am sure
its a registry problem or networking security issue but I cant find it.
I shared the Vista machine and printer as usual. I notice that on the Vista
machine it talks about password protection sharing . It has an option to
turn this off in the network control panel. Problem is the option is there,
it lets me see the two options to either turn it on or off. Lets me select
the turn it off and then apply button is active but after I hit apply it just
stays the same and does not turn it off. Nothing greyed out, etc... Alll
buttons there and active it just wont apply after I select no password
needed.
Again the Vista can see and access the XP machine with no permissions or
password problems but the XP machine cant access the Vista. The Vista
machine is the one with the printer attached and all the main files that I
need.
Any help would be great.
