When you try to log on to a Web site by using Microsoft Internet Explorer or Windows Internet Explorer, you receive the following error message:
The page cannot be displayed.
The page you are looking for is currently unavailable. The Web site might be experiencing technical difficulties, or you may need to adjust your browser settings.
This symptom occurs even when the hard disk has sufficient available space for caching Web content.
This issue occurs when the Index.dat file in the following folder reaches a size of 16187392 bytes:
<Drive>:\Documents and Settings\<User_name>\Local Settings\Temporary Internet Files\Content.IE5
<Drive> is the drive on which user profiles are stored.
<User_name> is the name of the current user.
To resolve this issue, delete the Index.dat file. By doing this, you restore caching functionality.
The amount of data that Internet Explorer can write to the disk cache is also limited by the following factors:
The number of items that Internet Explorer has written to the disk cache
The size limit that is specified for the cache in Internet Explorer
Note Internet Explorer uses the Index.dat file in the Content.IE5 folder to cache Web files on a local disk. When the Index.dat file reaches a size of 16187392 bytes, new content cannot be cached to the local disk.
