This past week I have had two computers Windows 98 mysteriously lose connection to the network and the only way I can get them back on the server is if I change from automatically finding an IP to configuring the information with their old information. Yesterday I had one and today another computer did the same thing. I can get them back on the network but I have to go into TCP/IP properties and put in their IP address, subnet mask, gateway, and DSN server Ip's so they can connect to the network and web access. I also have been getting prompted on these two computers for the Windows98 cd to do something with the secur.dll file????? Please help leaving for vacation tomorrow and do not want to have problems while I am gone from the office!!!

Thanks!
