Hi Ali,


Not sure if this is the problem with your vista clients but can you try upgrading the nic drivers for your vista clients? Atleast for one and see if that brings any improvement.


Vista Serive Pack may address your issue (they are trying to make Vista play well with others).


Here is a list of fixes it has...it may be a clue to as to whether your issue is common and is being addressed. The Vista SP will release in February I believe.

Hi Ali,


Can you please confirm what is the gateway address configured on your vista clients and what is the gateway address configured on your xp clients?

Hi Ali,


Is there any specific reason you have configured HSRP as well as GLBP on same interface which is vlan 20? Also I see on your DS2 your ip on vlan interface and virtual ip is same? Is that a typo error?


Can you try configuring one of your vista client with HSRP virtual ip which is 100.20.20.3 and see the results?

Hi Ali,


Proxy ARP can help machines on a subnet reach remote subnets without configuring routing or a default gateway.


As your machines already have default gateway configured you can disable proxy arp using the command you mentioned but I don't think that will bring any difference in the behavior as your XP clients are working fine in same configuration correct?


Oki my mistake I overlooked your config and thought it is configured with HSRP also.

Ankur
