There seems to be a bug in the Draytek 2860 router, even though I had changed the management ports from the default 80 and 443 to 8080 and 8080. I was still unable to port forward any 443 traffic and would end up getting an 404 error page from the Draytek 2860.
The next thing I tried was to disable the SSL vpn in the remote/vpn section, this made a change as I now no longer got the 404 error page from the router while trying to browse to https://mail.mydomain.com but still the port forwarding was not working.
After drilling down deeper into the Draytek 2860 SSL VPN settings, I changed the port the SSL VPN uses from 443 to 44444. I did not think that this change would make a difference as the SSL VPN was disabled, I was wrong! The 443 port forward started working, so even though the SSL VPN was disabled, it seems that port 443 was still in use by it.
When moving mailboxes from Exchange x to Exchange 2010 the bad item limit is set at max of 50, if you have a mailbox that has more bad items than that you can do the move request via the Exchange Management Shell using the below command
Change the Alias goes here for the mailbox alias keeping the ‘ ‘ as an example if we were moving my mailbox we would enter ‘William Rendell’ Also change the 100 for what ever value you want to set for slipping bad items.
First of all I list all the rules including line numbers like this;
iptables -L -t nat –line-numbers
I then look at the output that will be similar to the below
In this example lets say I want to delete rule number 2 in the PREROUTING chain, I would enter the following;
iptables -t nat -D PREROUTING 2
In English the above line means remove line number 2 from the PREOUTING chain, I would then run the first command again to check my iptables file, then save the iptables file and restart the iptables service.
iptables -L -t nat –line-numbers
service iptables save
service iptables restart
All the above is carried out running on Centos, you may have to edit slightly for your particular distribution.
The database size limit for Exchange 2003 standard is 16GB, however SP2 for Exchange 2003 allows you to remove that limit. The default size for priv.edb after installing SP2 for Exchange 2003 is 18GB this can easily be changed for database sizes upto 75GB per database.
The steps below explain how to increase the 18GB limit by editing the registry. Edit the registry at your own risk, I will not accept any responsibility if you run into problems.
On the Exchange 2003 server, run regedit
Navigate to the following registry key
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MSExchangeIS\Server name\Private-Mailbox Store GUID
Create a new DWORD entry called “Database Size Limit in GB”
Change from Hexidecimal to Decimal and enter the value of the size in GB that you wish the maximum DB size to be.
Exit from the registry editor
You should now either restart the Information Store or dismount and mount the store in question.
The maximum database size for the priv.edb should have now been increased to the value you set in the new DWORD
