I get error when powering Mk 5.7

Hello all,
I installed win server 2003 enterprise edition on host with 1800 Ghz, 256 Ram, 40 Gb HD. then I installed Isa server on that host after that I installed Vmware version 7, Finally I make a guest on that Vmware which is MK 5.7. But when I try to power on this guest Mk 5.7 I get error say: not enough physical memory is available to power on this virtual machine…

How I can troubleshoot this probelm?

thanks

That has nothing to do with Mikrotik. You host computer only has 256 RAM??? Plus you are running ISA server, plus you are running vmware???

Windows 2003 itself needs a minimum of 512mb RAM, and 1GB recommended.

Anyway, go into the VM settings for MT and reduce the memory it uses.
