Inconsistent pinging

[mrbusy]

I have a client who is experiencing problems with network connectivity.

He has a win2k pro workstation on which he has some software running which he would like to access accross the network. From some PC's the app server PC is not accessible and cannot be pinged by name or by IP address. This appears to be random and changes from day to day.
We have discovered however that if you ping PCs which cannot connect from the app server workstation then return to them they are now able to connect.
Ive advised the client to change to a static IP addrees, which didnt seem to help. Im not aware of any firewall or packet filtering software running on any of the PC's. The network is 192.168.1.0 / 24 and both the server pc and the client pcs are DHCP. All workstations are win2k pro. The network is very small and has less than 20 hosts all wired into the same netgear switch.

Any thoughts? Help would be appreciated.

The Win2k pro workstation can only accept 10 connections at a time. Add to that you likely have autodisconnect issues, and Computer Browser fights if you have let all of the workstations participate in Master Browser elections.

For Master Browser issues, spend some time at Forum member Bob Linn's sites for suggestions about reducing election battles for Master Browser status:

Put a server in. Provide proper infrastructure DNS/WINS etc and that will remove connectivety issues.

Or the switch has something wrong with it.

Are any of the cable runs longer than 100 meters?

Oh, I have been caught out with auto-disconnect before and it was flakey RJ45 sockets on NIC's that where the problem.

Just some ideas.
