All in a day’s work

While most enjoyed a really long weekend, I was at office running test cases and fixing bugs that aren’t mine... Last Thursday, which was supposed to be a half day of work I worked till 2 A.M. (Friday). Most of the hours spent not on work but the following exceptions, all in one day -

The request failed with HTTP status 401: Unauthorized. : This kept coming and coming - I just couldn’t access the webservice - not through the browser nor through a client. The following link helped -

ORA-12154: TNS:could not resolve the connect identifier specified. : This is actually my fault - I had two oracle homes 9i and 10g and then I had two TNS.. the following helped :

Server did not recognize the value of HTTP Header : This comes - as I understood - because of corrupted ASP .NET temporary files - if you remove them it would work.. but if you don’t know what corrupted them this would strike again and again.. the following like helped

Web service initialization failed. : namespace of the proxy class automatically change to http://tempuri.org/ only cleaning VS cache and temporary ASP .NET files and recompiling and running the asmx helped. But it didn’t fix the issue. I made sure http://tempuri.org/ is not found in any of the files.. oh boy this gave me enough.. nothing really helped me on this one...
