I'm on Windows 7 and use sharepoint on windows explorer to work on multiple documents. It was all working fine until a few weeks ago, then I started getting the "access denied" message quite a lot, now I log into sharepoint, use open in explorer and it maybe lets me open one or two files before kicking me out telling me I don't have permissions etc. My trusted sites are all in, I have the hotfix installed, I've checked all my settings (I'm a global administrator user in SP), so I'm pretty confused as to why it's suddenly being difficult. The problem also exists when I log in as myself from other pc's.
Any advice appreciated, before my pc goes through a window.
