Anyone else experiencing trouble connecting various microsoft www and ftp sites? I put a Sniffer on the line and found that I have a part of a web page come up and then the connection is reset. This is using Netscape Communicator4 on both NT and SPARC Solaris. If one uses IE3 it works better. I find this highly suspicious. Also straight ftp from a unix system is very slow if you get in at all. I think we can all agree that the tcp/ip stack on sparc solaris 2.5.1 is not likely broken (patched to current level, January '98, just in case) where NT might be suspect even 4.0 w/service pack 3. One possible problem I consider is that I have Path MTU discovery turned on in all my routers interfaces (Bay RS12.10). My path to microsoft is via Alter.Net . The local Ethernet MTU is 1518 but the UUNET circuit is 1600. The packets I see come by with "don't fragment" set for several and then one that does not have DF and then the TCP reset comes in. Suggestions and opinions? Thanks Dana Hudes Graphnet
