Messages not sending in Exchange 2007
Posted on 2010-11-08
I'm having trouble sending email and accessing websites on my windows sbs 2008 server. I'm not entirly sure if they are related, but it is causing the company a huge amount of problems and i just can't seem to fix it - so any help will be greatly appreciated.
Emails usually send but occasionaly they all just get caught imn the queue and don't send - with the error 421 4.4.2 on the queue. There doesn't seem to be consistancy..it just normally works but occasionally doesn't. It is similar story with the internet access - it slows right and then just stops loading websites on the machines. I can't seem to find a valid fix for it, restard the DNS/flushing the cache both don't seem to particually help, after x length of time it just starts working again. Even if i just enter/ping a IP address it doesn't work, so i don't think its a DNS issue.
This is my first serevr install set up so i may be missing somthing really obvious - but i just can seem to find out what.
