I have two windows servers in a remote data center, and there are issues connecting to them.
The Servers have DNS, Websites, MySQL and Email Services on them.
Access to websites is NOT a problem. This type of connection works perfectly.
MySQL seems to work flawlessly too.
DNS... I am not sure, it seems OK, would like some (non-single) tests I can perform.
RDC. Occasionally I am disconnected - even if only briefly. Sometimes, I try to connect, and it fails instantly, then connects instantly next attempt.
Email... This is a MAJOR issue. SMTP and POP are not working every time, but also do not fail every time:
Desktop > Office Server > Problem Server = Works fine every time.
Desktop > Problem Server > Other Server = Works fine every time.
Desktop > ISP > Problem Server = Email goes missing..!
Desktop > Other Server > Problem Server = Delays, but only sometimes.
As this seems to have affected the two servers at the same time, I suspect this is a network - related issue. On Server is 2003 SP1 the other is 2008r2 SP1
I have done tracert, which shows no problems, but then this is an intermittent problem
Anyone have any tests I can run to see it I can find the problem?
