In Windows XP
disable firewall. Also try to setup VMware with a power user.
In Windows XP turn off all the effects that it does.
BTW, why are you running VMware in Windows. I can see running VMware in LINUX and trying to run your favorite windows programs. Windows especally Windows XP is very, very, very bloated. Windows only gives 60% of the processor to the user. The rest is for lousy windows.
