I have a single Excel 2000 file that will not open. The message is
"xxxx.xls" cannot be accessed. The file may be read-only, or you may be
trying to access a read-only location. Or, the server the document is
located on may not be responding."

I checked the check: it is not read-only. I know that the location is not
read-only or otherwise blocked, since we are able to access other files in
the same folder. We have tried this from different computers on the network
and all have the same problem. This is the only file with this issue.

I did notice that the inaccessible file is larger than it should be. We
have a number of similar files and they are all about 300 to 500 k and this
one is 1.7 megabytes. I don't know if that is helpful or not, but maybe
that will provide a clue.

Thanks!
