I had a 2 hour layover and was browsing the newsgroups. A person posted a question wondering about interview questions regarding IIS and .NET 2.0. Iâ€™m sure there are many other questions that I didnâ€™t think to ask, here is the list I came up with. If you have any questions, feel free to post them to the comments and Iâ€™ll update the thread.
PS: This is meant for a ‘systemsâ€™ or ‘itproâ€™ type person and not necessarily a developer type individual.
