Quota Limits

Ok, After setting up roaming users I found that if I create files over 5MB or somthing it takes around half an hour to save to the server. So i need to know how to set quota limits on users,

My server is on NTFS and my client is on FAT32 but only NTFS does quota so im in trouble

Is there a way from the SERVER to set the quota??

Thanks
