First machine it is Windows server 2012 with DHCP, IIS an WDS roles, second with setting boot from iPXE.iso, downloaded from official site. It's boot, obtain ip, load small files, but when i try load large file all freezes near 32KB. See attachment.

Not sure where you get your 32kB figure from: bootmgr in Windows Server 2012 is 398156 bytes, so 21% of that would be around 81kB.

Are you able to press Ctrl-C to cancel the download, or is the VM completely locked up?

Which virtualised NIC are you using? ("ifstat" within iPXE will tell you, if you're not sure.)
