Dear Sir,

I'm an Admin. gay of a network domain. I recently received complains from users that they no longer access the FTP service on a particular host after the IP address of that host was changed. Could anybody tell me what's gone wrong ?

Thanks a lot !!!

you have not mentioned what operating system u r using and the problem is on Local network or internet. If u r using windows 2000 servers and workstaions then u have to change the DNS IP on each client if u r not using DNS enabled DHCP server.

When you change the IP address to the workstations did you change the DNS setting on TCP/IP properties? I hope not. I will check the WINS server also to make sure the new ip addresses has been synchronized in the domain. Go to one of the workstations with this problem and perform a PING to the FTP server by IP address, then ping by name, also try to ping any workstation or server in the network. If your are using DHCP do a release ip address to make sure that you will get a new ip address from your DHCP server.

Hope this will help you.

Besides the WINS and DNS, you may want to check if the users have the old IP address hardcoded in their local host file.

Do a search/find file in the Windows or Winnt directory for "host" (no file extension)
