Sudden loss of ping
Posted on 2014-02-06
We have a mature network, and fairly plain vanilla. 200 Pcs, 15 servers.
I'm the sys admin.
I've found 5 static IPs I cannot ping from my PC; everything else I can ping. I don't recall this problem before. (My PC has a dynamically assigned IP)
I rdp into a server; that server can ping these 5 IPs (and anything else I try)
Where do I start looking to solve such an odd problem?
I have Win 7, we have Win 2003 and Win 2008 servers.
All machines mentioned are on 192.168.150.nnn
Static IPs are 150.55 and down. DHCP scope is 150.56 and up (into 151.200)
(Possibly red herring; we have a current problem with a switch, causing BAD_ADDRESS lines to fill up the DHCP scope. Sometimes we delete them if a user can't get on, and they then get on. Doesn't seem to affect loged-on users. We're working on it. I'm confident my non-ping problem pre-dates this.)
