Are you sure you're using CAT-5 cable? You say the NIC's are forced at 100/full -- how about the switch ports? Is there adjacent "noise" that might be emitting across the network? Do you have old vs. current switch HW? Is it up to date, microcode? VLAN's -- are you sure it's a point-to-point and not getting re-routed due to DNS "mistakes" (eg, any potential router involved, multiple DNS entries for the same hostname, local hosts file on the client, local routing table on the client)???
Your msg got garbled when stating specifics of your client situation... is the problem only on one (of many) clients using the same switch? Finally, what OS platforms (and switch vendor & model) are involved? These are buggers to solve, unless you can find some consistency -- eg, one client fails but others run fine (typical, and helps reduce the focus to identify the delta between good client and failing client -- for Win2K, we've seen flaky OEM-NIC's cause this kind of problem; also, one switch vendor didn't work well with forced 100/full, simply insisted on auto-negotiate.) ----- Original Message ----- From: "Jim Healy" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Monday, April 15, 2002 11:25 AM Subject: TSM network problem > Can any of you network gurus help me out with a TSM problem? > > We currenty have an isolated 100mb ethernet network for TSM. > We have three NICS in the TSM server, each attached to a seperate V-lan > We spread the servers backing up across the three v-lans > > We are having on clients on one of the vlans that intermittently get > "session lost re-initializing messages" in the dsmsched.log > > When we ping the clients from the TSM server we get no seesion or packet > loss > > When we ping the TSM nic from the client we get intermittent packet losses > > We replaced the NIC in the TSM server > We replaced the cable from the TSM server to the switch > We replaced the cable from the client NIC to the switch > > We've ensured that both NICs are set to 100/full > > My network guys are out of ideas any body have any suggestions?
