Thanks for reply. My windows version is 32 bit Windows server 2003 Enterprise Edition Service Pack 2. Even I have not tried /PAE switching, I will try this and get back to you. And one more thing I have an idea of installing windows server 2008 R2 Standard version on this server, will it support? Please let me know Chris. Thank you.
