here is the scoope we have a SBS 2003 domain and on that domain we have another 2003 Server running a erp system. I have deployed several Windows 7 boxes with no problems. I however have 2 pcs that will not communicate with the 2003 server it gets dropped packets and does not pull anything off of it. The wierd part is some days it works perfectly fine. The nic's power settings do not turn it off and they are 2 different versions one is windows 7 pro 32 bit and the other is windows 7 ent 64 bit. The drivers are all updated. On another note pings from the server to these machines act the same way dropping then sometime is will reply. So they refuse to talk to one another i have no other issues with the countless other window 7 boxes.

Other note in safe mode it does the same thing also it does not matter what user im logged in as it still does it.

Hi, Have you tested the result on Safe Mode with Networking? Or you could try to perform a Clean Boot to troubleshoot this issue. As your description, the two computer work fine before, I want to confirm the following questions: 1. Did you receive any error message when you connect to SBS2003? 2. Can these Windows 7 clients access other resources on the network, such as share folder? Now, please take the following steps for collecting information: 1. Please try to ping both computer name and IP Address for test, check what the result is. 2. Collect ipconfig /all on both the server and client sides. 3. You could also go to event viewer to check if there is some error information about your system.
