Hello, I setup a workgroup to test windows logo, host OS is windows 2008 server R2 SP1, client OS is windows XP SP3, the IP is static, and firewalls of host and client are all closed, and the guest accounts are on, but I didn't find the client in default pool, could somebody help me to solve this problem? BTW, if the client OS is windows vista sp2 or windows 7 sp1, the host can find the client. The WLK version is 1.6 Thanks.

Hello, what "default pool" are you talking about?Best regards Meinolf Weber Disclaimer: This posting is provided "AS IS" with no warranties or guarantees , and confers no rights.

WLK is windows logo kit for windows certification(WHQL), after install DTM controller and DTM studio, there is a "default pool" in host PC, and there should be some client PCs in "default pool", but I didn't find it when the client PC OS is WinXP SP3.

Hello, Thanks for your help. I already found the root cause, it's a PC and router compatibility issue, I changed another PC and router, the problem has been solved.
