SharePoint Designer cache

SharePoint designer plays a very important role in terms of site

customizations. If it struck somewhere then it will be a big problem.

Would like to share such incident based on the same. By default all

sharepoint sites are blocked in designer in our enviornment, so if any user

wants to customize the site then he has put a seprate request for that

then site will be allowed to open it in sharepoint designer.

What happens exactely: I have allowed site to open in SPD but user was

not able to open and getting access denied. I tried opening the site in SPD

from my side then it opens fine without any issues so one thing was clear

that this is machine specifc. here cache comes into the picture.

1.   Close SharePoint Designer.

2.   Open My Computer

3.   Go to %System Drive%\Documents and Settings\%user%\Local Settings\Application Data\Microsoft\WebSiteCache

4.   Just delete all these directories and everything should work when you boot SPD).

5.   Restart the SharePoint Designer.

In case of any queries/questions regarding the above mentioned information then please let me know.
I would be more than happy to help you as well as resolves your issues, Thank you
