I recently upgraded a switch model WS-C2950-24 from IOS 12.1.22-EA1 to 12.1.22-EA12. After extracting the tar to flash I received an error Premature end of tar file. After reload, the new IOS version is running but there is now a problem with Web-Based Management. When using IE and other browsers, the display cookies are missing or just show little red x's. Is there away to correct this or load the html file?
