Hi having an issue where intermittently the SMTP service principle name (both NETBIOS and FQDN) vanishes and all outbound external emails stop . I can put them back in using setspn.exe setspn.exe -a smtp/server server setspn.exe -a smtp/server.domain.co.uk server but then after a random period of time they disappear and need re-entering. Any ideas why these are being dropped ? Its exchange 2010 on a 2008r2 server . Single server doing everything on exchange.

Ok Thanks to everyone for the info

I have got 3com 7760s, 8760s, 8250s, 7250s . They all appear to have options for changing between standalone and managed but not sure how would go ahead with that or if its misleading etc .

Yep Brain kicked in aftr I had written that all in and have set up a computer on old range and it can see them all and have now been able to ping / browse to relevant ports . So now is there any way I can get these talking to some sort of interface where I don't have to change every single point every time i want to change a setting ?

I think this may be our problem , About 6 months ago we migrated to a new domain and in the process a lot of settings changed regarding netmasks and default gateways . As I understand it currently we have 255.0.0.0 as the netmask where previously everything was on 255.255.252.0 The default gateway has also changed . A colleague now remembers at some point there was a central control program but this was on a computer that has now been disposed off .

I have a list of IP Address but I cant browse to them and I cant ping them , so not sure if it is old information or there is something I am doing wrong ?

I have been visiting edugeek for a while for info but never had to post before but I am totally stranded with the WiFi here at school . We have 30 odd access points at the school all 3com which I am led to beleive are about 7-8 years old . I've only been here a year myself . The WiFi works but is completely unsecured ( well not completely someone has hidden it so that it don't broadcast , but everyone knows the name so its effectively open to students and staff a like ) We don't seem to have any way to control the WiFi and it seems to work because its always worked but nobody here knows anything about it . I have to find a way to secure it but i have no idea where to start .... Has anyone any advice for where I need to start .Ideally I need to get the Network secured with at the very least a password . I managed to locate a software disc called Wireless Infrastructure Device Manager , but when I try to run it it simply states No Network Adapter Available and auto closes .
