This article was previously published under Q301673 SYMPTOMSWhen two client computers try to use the server message block (SMB) protocol to connect to the same server across a network address translation (NAT) device, the more recent client connection may reset the
earlier client connection. If a client and a server that use the SMB protocol over a NAT device are copying files, that session may be reset
when another client uses the SMB protocol over the same NAT device to the same server.
Note This problem does not occur when the server is
running Microsoft Windows NT 4.0. CAUSE When a new connection is established to a server, the
server checks for previous connections from the same client IP address and
deletes any previous connections. Because NAT acts as a proxy for the SMB protocol by using the
same IP address from the two client connection requests, the earlier connection
is terminated. RESOLUTIONNote The latest service pack is not requried to resolve this problem for Microsoft Windows Server 2003-based comptuers.
To resolve this problem, obtain the latest service pack for Windows 2000. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:
