VMware issue

Ever had an issue where the guest OS has trouble copying files from the host OS? It will start, and then cut out.

Check the event viewer on the host. If you see bunch of Denial-of-Service warnings/errors, then you have found your problem. You need to turn off DOS on the host as follows. Now I am sure some would say that you are opening yourself up to some security problem, but I always trade security for convenience, so here is what you do.

1. Launch regedit, and navigate to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\LanManServer\Parameters

2. Create a new DWORD Value called DisableDos, and set its value to 1.

3. Maybe reboot to make sure.

Exchange 2007 message size limits

Not as simple as it used to be in Exchange 2003. Have to set it at the transport level and also at the send and receive connector level. To set to, for example, 50MB, need to do the following:

Set-TransportConfig -MaxReceiveSize 50MB
Set-TransportConfig -MaxSendSize 50MB
Set-ReceiveConnector -Identity (connector name) -MaxMessageSize 50MB
Set-SendConnector -Identity (connector name) -MaxMessageSize 50MB

Older Speedstream DSL modems

I learned today that older Speedstream modems, like the one pictured, a 5100 model, do not give you an IP address, which would otherwise allow you to configure them. As far as I know, they do not have a web console. And they will not do PPPoE for you, either. If you have a router, you need to configure it for PPPoE. If you do not, you have to create a new network connection, and follow the prompts for creating a PPPoE one.
