Our Web dispatcher is showing "page cant be displayed" on the front end when I try to hit the gui from IE (/sap/bc/gui/its/webgui) and I am unable to hit the admin page on the front either, however it is accessible through sap mmc. we have recently upgraded to 7.73. We have 15 WD running on the host server and all are working fine except one. there are no errors showing in the trace file and connection to MS looks good. running sapwebdisp.exe -checkconfig returned with everything "ok" and no errors. pse files are good to go and certs are up to date. I can also telnet to MS. I have tried un-installing and re-installing and still I get "page cannot be displayed" on the front end,
