A few experiments to try.<BR /><BR />Hope that helps Tue, 11 Oct 2005 09:37:12 GMT Derek Whigham_1 2005-10-11T09:37:12Z https://community.hpe.com/t5/operating-system-linux/nc7170-problems-on-dl380-g1/m-p/3646652#M85348 We have 7 DL380's the same apart from software ie one exchange server, one sql server, one file server one Domain Controller. OS Win2000 sp3 across the board. Connects into 3com superstack 3 switch 3870 48 port. this port is connected via 6 cat6 cables in star topology to other 3com 10/100 switches. Since putting in the NC7170 we have experianced dropped connections between software and SQL, problems installing the cards in some of the servers - they just wont recognise them, overall performance issues. The print server is slow to respond. Any pointers would be greatfully recieved.
