I installed Magento without any error and every permission and step described under official installation guide I followed. When the installation finished, I can see that Front end is working fine and when I go to back end(Admin panel), I can login fine and dashboard is displaying BUT when I click on any link like Sales > Orders the page says “The service is unavailable.” and this is same hapenning with almost all links of Admin panel.
Also, there are very few links which are working like Category List. This seems to be really strange.
I am using IIS7.5 and every setting seems to be fine as some other PHP sites are working very fine.
Can someone please help.
