I have a network with various subnets and on subnet 1 I have an Active Directory server providing LDAP. on subnets 2 and 3 I can connect to this ok using the ldp.exe command in Windows. However, when trying to connect to this from subnet 4 using ldp.exe and the default TCP connection it fails to return anything (error 94), however if I select the option to make it connectionless (UDP) then it works fine...??
The connection travels through an ISA server / Router to get to the LDAP Server, however this is set to allow all communications for these subnets, and allows other subnets to work fine (as they route through this too), including the ISA Server itself - all can connect/bind to the LDAP server.
I have now tested the server in question in each of the subnets - and it also works in these areas, so it appeared to just be this subnet that was at fault, so I have changed the IP range for this and it still has the same problem - I have also changed the hardware switch for this area, as I thought by some remote chance it could be this, though this also didn't make a difference. Having moved other servers into the subnet in question - these also cannot bind to LDAP with ldp correctly - I've concluded that this subnet just isn't my friend.. Though to the best of my knowledge it is configured in the same way as all the others.

Can anyone shed some light on what this might be ?
Thanks
