1. http://support.microsoft.com/?scid=kb;en-us;314882 notes the 10 connection limit for file services. However your question is not about that but...
"how many concurrents users will win xp pro 32 bit will allow ?"
If I take just that question and count terminal server (it's a scaled down version in Pro) then the count is just 2.
2. That question has some really deep answers on google.com. Have you read them? Also, since this is a 32 bit VM, some find it doesn't pay off past 1GB. What test have you done to show that you need 2 or more GB?
In closing, Linux can serve up your 20+ file connections and more for a pittance of what Windows 2003 Server costs. Not only that, but if you have a 64-bit Linux OS you can shoot the moon on the RAM.
1- how many concurrents users will win xp pro 32 bit will allow ? (what i am trying to know is if i install an application on (a machine running win xp pro 32 bit )that is server application where 20 users can use it , i would like to know if all those users will be able to run that application installed from that Machine i an trying to use this machine acting as a server but running win xp pro, since win 2003 server with 25 user licenses is to expensive for us right now ? of course i will have hardware computer capable of doing this with a dual core processor and enough memory and a fast hardrive
2- I know that win xp pro 32 bit is limited to only use 3 gb of memory or just recognize 3 gb of memory and for example if the motherb of this computer use dual memory then in order to have 3 gb on this computer i have to install 4 gb(cause of the dual menory requirements), i would like to know if there any kind of trick utiltiy or whatever to allow windows xp to fully recognize 4 gb, i know xp 64 bit will allow to do that as 2003 server OS and vista too but the application that i will install won't run on xp 64 bit, 2003 and Vista, if you know of any help it is very apprecitaed, again excuse my ignorance
Thanks a lot
