I recently noticed that my computers get a lease and use it for the day and\nthen when they shut down release it. That's normal. Then, the next day,\nsomeone else gets the IP that machine had been using. Our lease times are set\nto about 2 weeks. The DHCP server is Windows 2003.\nIn the past those IPs would not be given to someone new so that when the\nfirst computer connected again it could get the same IP that it had before.\nThis way, computers tended to always have the same IP. By the way, the PCs\nare Windows XP.\nThe problem with this is that WINS seems to not be releasing the registered\nname; so, I can ping the name of a computer that is off and it might respond\nbecause some other computer now has the IP that WINS has registered with the\nname. Also, if I use sp_who with SQL 2000 server, it might show a connection\nthat belonged to one computer yesterday, but now even though SQL shows one\nname, it is actually a different computer. This seems to be because the\nconnection to SQL is not being terminated even though a client computer may\nbe turned off. So, it keeps the name and when a computer with the same IP\nconnects, it seems to think it is the same computer. Any ideas? How can I get\nDHCP to give the same IP always to the same PC? Is it because the PC must ask\nfor it and for some reason it is not?
