Exchange will stop receiving email once the hard drive is almost full. To solve this add another drive and move your database..reboot and all done. The reason for  this is the EdgeTransport.Exe.Config is set to EnableResourceMOnitoring value=true. Temporary change it to false.  The file iis in the "bin" folder. Restart the "MicrosoftExchangeTransport" service. Ensure that there is at least 20% free space to make exchnage run again


Dont forget to move the Exchange Mailbox database as follows:
Organization Configuration/Mailbox
Database Management tab
Move Database Path
Enter New path and move
Yes to dismount
All done and be happy again :)

IGMPv2 network flooding can bring down the entire network. Identify this issue with Wireshark than do the following 2 steps:

1. Enable IGMP snooping at Layer 3 switch. Layer 2 may not have or might not be enabled by default.

2. Identify compromised hosts and disable Multicast with the following command "net sh int ipv4 set global mldlevel=none". Than verify "netsh int ipv4 show global mldlevel".

Note: some basic firewall low ends do not have a filtering for IGMPv2. So if you buy cheap stuffs of course the risks is higher.

Download and Install "PDFill". All done :)
