Hi All,

we have new 2 65009 E-series switches and was planned to Vlan implementation,DHCP,HSRP (redudancy for Vlan).

both the Switches are running IOS System image file is "sup-bootdisk:s72033-ipbasek9-vz.122-33.SXH4.bin".

Earlier network was confiogured with flat network i.e 192.168.128.0/22 and 192.168.132.0/22 and all the server and clients were assigned.

After the vlan implementation we had observed performace issue with one of our application and when the changes were reverted back to flat network it works fine without any issue.

all the server were asigned with Static ip from 192.168.128.0/24 and 192.168.132.0/24 pool.

due to performance issue all the changes were revert back flat network.

after the changes reverted we had observed that wins was not resolving the user accounts.and we manually add the ip of wins server users was able to join the domain.

can any one please suggest me is there are some commands to executed or any bugs on iOS.

Attached are the configuration on both 6509 E-series switches.
