Please rephrase your request to what info you are looking for...
Are you saying you need a corporate xp license to install on pc's? - Contact microsoft for the best price and solution if it exceeds 20.
Less than 20, just buy the software instead of licenses (cheaper in the long run) and install it.
XP home will not connect to domains, nor allow more than 10 connections. Same with PRO.
If you are using XP PRO AS A SERVER... and have more than 10 pc's, you need to upgrade to either 2000 server, or 2003 server. There is no exception to this rule. The "Server" releases allow non-ending connectings as the home and pro versions will only allow 10.
If you're asking for technical help, please be sure to include all your system info, including operating system, model number, and any other specifics related to the problem. Also please exercise your best judgment when posting in the forums--revealing personal information such as your e-mail address, telephone number, and address is not recommended.
