MS Office – Cannot Add Trusted Location
KB ID 0001171 Problem I was doing a Domain/Exchange/RDS migration for a client this week. He had some Macros that he used for printing. Now Macros are something I know very little about. So I had made it clear, if he had problems with them, I would not be the best person to ask. So when the call came in, that they were having problems with Macros I cringed! As it turned out, the problem wasn’t the Macros at all, it was the...
Mac OSX – GNS3 Connecting To the Internet
KB ID 0001170 Problem I have a love hate relationship with GNS3, I appreciate it’s brilliant, (when it works).

So If you are reading this you have a DHCP server and you want to use it to lease addresses to clients that are on a...
Cisco IOS – An interface whose trunk encapsulation is “Auto” can not be configured to “trunk” mode.
KB ID0001167 Problem If you try and change a ports status, to make it a trunk port, you may see this error; Petes-Switch(config-if)#switchport mode trunk Command rejected: An interface whose trunk encapsulation is “Auto” can not be configured to “trunk” mode. Trunk Settings I don’t know if this is a throwback to when we had ISL trunking and 802.1q, but you need to specify the encapsulation before you can...
