Re: [Veritas-bu] Windows default maximum block size ... 64KB still ?

Hi Aleks,

This is from the old thread on this topic

http://support.microsoft.com/kb/907418/

this seems to be fixed in SP2

I have mine Windows 2003 media servers patched and still did not try SP2
After I applied the patch I was able to change buffer size to 256k

Good luck,
Boris
