XP Home and Xp Pro

[Bob W]

I was getting \\computername is not accessible. You might not have
permission... everytime I tried to access XP HOME via Workgroups and could
not see shares on it in Network Places.
Wireless between XP HOME SP2 and Media Centre 2005 (i.e. a form of Pro). I
could see all workgroups on each computer and could access
files on Media Centre from XP HOME but not vice versa. On the XP HOME I
went
to
start>run>regedit.HKEY_ LOCAL_
MACHINE>SYSTEM>>CurrentControlSet>Control>Lsa>restrictanonymous (NOT
restrictanonymousam)
and it was set at 1. I set it to 0 and I could access the HOME computer
from Media Centre and vice versa. However, when I checked it,
restrictanonymous had changed back to 1. XP Media Centre is set at 0 and
stays that way.
I can sometimes access the files on XP HOME using View Workgroup Computers
and now I can always access them via My Network Places. The 0 or 1 does
not seem to matter now for My Network Places. Not sure about Workgroups.
Any ideas why it changes back to 1? (sometimes without a re-boot).

Bob,

I can't find any reference to why this setting would change on you. If you wish
to, maybe we can find out a bit on our own. Regmon (free) from SysInternals may
tell us what's going on, if you set it to filter (Include) on
"restrictanonymous".

After running Regmon, it appears to be lsass.exe:956 that changes the
restrictanonymous value from 0 to 1. There are two files by that name in
c:\windows\system32 and in c:\windows\ServicePackFiles\i386. Both scanned
virus free with AVG. gcasServ.exe:3580 seems to have an interest in it
also. ntsf.exe:3684 also seems to either change or monitor it. All
necessary files but perhaps I have not set some permission properly?
