SP2 computer browser problems under WPA/AES

[nusr]

I have a network with 2 SP2 and 2 SP1 Windows XP Home PCs. Each PC is
connected through wireless NICs using WPA-PSK/AES encryption.

I want to designate either one of the 2 SP2 PCs as the PC to control the
master browser list. When I try the other 3 PCs can't access the PCs through
network neighborhood. I receive the familiar permission denied, contact
administrator error message.

If I designated either one of the SP1 PCs as the PC to control the master
browser list, everything works. All 4 PCs can see the list and access
eachother through network neighborhood.

Yes, I have the SP2 firewall service started but the firewall is "off". It
appears I needed the service started to even have the SP2 PC control the
master browser list. The list is only seen on the designated PC. Something
is diffinately blocking the list from being pushed out to the 3 other PCs.

Have no idea whether it has anything to do with sp2. Just a thought are you using any wireless utility? FYI, if you're using a router and wireless card, you need to ensure that both the router configuration page and the wireless utility have the wpa-psk password set.

Yes, each adaptor has it's own connection utility. The passphase is the
same for each connection and the AP. I can ping each PC and get to the
internet from each PC. It seems to be some running or not running on my
SP2 PCs that is effecting the master browse list.

 

[nusr]

I also want to add this. Switched back to WEP/128bit and I'm able to
designated any PC, whether it be a SP1 or a SP2 PC, as the PC to
control the master browse list. And all PC can see each other through
network neighborhood without any problems.

I have stop using wireless for quite sometime so i can only give you some
rough idea. If i'm not wrong, there's a option under network connection>
wireless connection, you can choose to disable using window option and use
the wireless utility instead (if i'm not wrong, window wireless is enable by
default, you need to untick it)

 

[nusr]

No, its something to do with SP2. Another test I performed was to
switch to WPA/TKIP encryption. The PC names are visible and accessible
through network neighborhood under this encryption scheme. AES and SP2
do not play well together.

Problem resolved.

Review:
4 PC in LAN. 2 Windows XP Home SP2 and 2 Windows XP Home SP1. All
wireless clients using WPA-PSK/AES security encryption. Equipment,
Linksys WAP54G, Linksys WRK54G, Linksys WPC54G, D-LINK DWL-G122, DELL
WLAN 1350 Mini-PCI, Netgear WG-111. No firewall active.

PC1: SP2, holds master browse list
PC2: SP2
PC3: SP1
PC4: SP1

PC1 could display/access all machines in list from Network
Neighborhood. PC2, PC3, PC4 could not display/access master browse
list. They each returned the "permission denied, see administrator
error message".

Fix:
Enabled lmhosts file lookup on all PCs.
Enabled TCP/IP filtering on all PCs to "permit all"

Now all PCs in LAN displays the master browse list sent from PC1 and
can access the shares through Network Neighborhood.
