When I am looking for random failures or looking to resolve performance issues, one of the first things I like to check is if there are any linked servers that could be contributing to the problem.

When choosing to use a linked server, it must be understood what the purpose of the linked server will be and to not abuse the linked server. Restrict the use of the linked server to a small scope and hopefully an infrequent use. For instance, I have demonstrated good uses of linked servers in my poor mans audit presentation and in my database restore solutions article.
