Hi, what are "clients"? I'll assume computers in general but if you mean specific software then please specify.
What layer are they losing the connectivity at? Can they ping anything? If so, what can and can't they ping? If an affected client can't ping something in the same subnet, then try to ping that affected client's IP address from that something. If it succeeds, then check the MAC address associated with the affected client's IP address in the ARP table of that something and compare it to the MAC address of the affected client. If it turns out to be different than that means that you have duplicate IP addresses and you should double-check the DHCP configuration. You mentioned that rebooting the client helps. Did you try 'ipconfig /release' and/or 'ipconfig /renew' to see if that helps, too? It might also be interesting to see if there are any machines that are never affected. It can be tricky though as it is not easy to distinguish between "not affected" and "hasn't happened yet". Is AD Active Directory? If so, do you perhaps mean that people can't log in after a while? If you mean something else, then why is it relevant that they have AD (or what is AD)? How is the problem related to the remote site?
