i was having a program running since many years on a peer to peer network.
for file sharing i was using

use in 0 shared

there was one computer which had the data and the exe

to map the drive on the computer i was using

net use p: \\\

recently we upgraded and we started using domain based server (DHCP)

now instead of something1 we now started using 192.168.111.230

but the problems have started the moment the second person logs in.

sometimes the program starts, sometimes it does not, if the prgram does starts then it gives errors after some time
