Developer hangs while renaming folder / service

Dear All ,

My developer hangs while renaming a folder or a service. Same problem occurs if we try to “Lock for edit” a whole folder.

This started after we installed a new 6.1 IS server . I haven’t applied any patch/SP other than the one given by default by installer (IS SP2 and TN SP1).

Thanks in advance for any ideas at all,
cheers
