Strange network issue (ZIP file fails CRC test over VPN)
- by Joe Schmoe
We have a server in the office running Windows Server 2003
Our office is connected to our datacenter via hardware VPN (Linksys RV082 router in the office to CISCO router in the datacenter).
There is a job that runs on the server in the office that does following: ZIP certain files from the server using 7Zip, copy ZIP file to a network share in the office and verify ZIP integrity, copy ZIP file to a network share in the data center and verify ZIP integrity.
Problem is - verifying ZIP integrity for the file in the data center always fails. However, if I run 7Zip on the server in data center that exposes that share ZIP file verifies just fine, so it is not actually corrupted during copy operation.
Additionally, I tried running ZIP on other computers in the office to verify ZIP file on datacenter file share and it verifies OK.
I tried plugging server to the same network port where my workstation is connected using different cable (my workstation doesn't exhibit this problem) and ZIP verification still fails.
So the problem is local to that specific server.
On network adapter properties for the server in question there is no "Advanced" tab where one can usually configure a lot of network settings.
Network card driver is up to date (Windows Update doesn't find anything newer and Lenovo website doesn't have any drivers for Windows 2003 for this computer model).
Is there any other way to configure network setting via command line? What settings could be relevant to this problem?
