Having All kinds of issues with NC! Please Help

I have had the week from hell largely caused by NC and NC installations.

  1. We have our own NC implementation that from our work network the two administrator accounts take about 30 secs to log into.The web page is instantaneous. All other accounts from our network are fine, just the 2 admin accounts.

  2. We can remote to a customers PC and login to the same admin accounts and login is just fine. It only is slow to login from our network >30secs.

  3. From my network and the same PC I can login to other NC instances just fine, it is only our internal one and only the admin accounts.

Packet capture looks fine.

Any ideas

I feel like this may be related to the brute force plugin. Have you whitelisted your internal range(s) to avoid BF rate-limiting you?
