Proxy master flag being ignored?

Hi All,

I'm having a problem with OpManager where, we used to use a Proxy Server but have discontinued use. We've changed the default gateway on the OpManager server from the Proxy Server to our new (non-proxy) gateway box. However, all our external URL monitors are now failing.

I went into the Admin module and unticked the "Enable Proxy" flag and tested the external URLs again and am still getting "The URL http://www.chemalert.com.au/ is down, Reason : Host Unavailable". Yet I'm able to log onto that server and access the site fine.

Any ideas on how to debug this and has anyone experienced it before?
Thanks
Brad
