Does anyone know how to find the IP of a managed switch (Netgear) on a W2k3 server network? Tried the DHCP, ARP, IPconfig and Firewall with no luck.

If its a managed switch, then there is probably software used to manage it. Some times that software can "discover" devices on the network. So if you install the software and it has that feature, then it may find it.

Ah yes, forgot to mention, have lost the software and you can't download it from the NetGear website, I'm on the case with their 'support' department right now.

connect via console cable to the serial interface and logon. The menu will tell you the ip address. This is where documentation really helps Golly gee wilerkers everyone. Learn to Internet Search

Wanderer's right. I'm not familiar with netgear but all our Cisco, 3Com and Nortel Baystack managed switches have console (serial) connections. In the case of the Cisco's, they use a cable with a DB9 on one end and an RJ-45 on the other (or RJ-45 on both with an RJ-45 to DB9 converter on the end plugged into the PC). The Nortel Baystacks and 3Com's require DB9 to DB9 cable. I'd wager yours requires a DB9 to DB9 type cable. Once you're physically connected you should be able to use any terminal emulation program like Hyper Terminal or my fav, Tera Term to access the management interface. All the switches I mentioned above require your term program to be set to 9600 Baud, 8, No, 1.

Connecting to the console port is the best and easiest as long as you have physical access. However, if it's at a remote site and no one there is allowed access, that won't work. In that case you could use nmap (or other scanner) to scan your network. This is exactly what I'm currently doing on our network to discover unauthorized devices attached to the network. http://www.insecure.org/nmap/

ok, so I managed to find the CD, turns out that two switches had assigned themselves the same IP...
