When you manually scan Windows 2000 or Windows NT with Norton AntiVirus Corporate Edition (NAVCE) 7.x or Symantec AntiVirus Corporate Edition (Symantec AV), you see the error message "Could not start scan. Scan engine returned error 0x20000058."
If you stop the Norton AntiVirus Client/Server service, then the problem does not occur. On most systems, stopping and then restarting the Norton AntiVirus service after system start-up solves the problem until the next login or restart.
There is no single cause. Several reasons for inappropriate display of this error message have been identified and addressed.
There are multiple reasons for this error message to occur. In many cases, NAVCE or Symantec AV has perceived an error condition that, in fact, either does not exist or should not affect processing.
Later builds of NAVCE and Symantec AV included corrections for many of these conditions. In most instances, upgrading will solve the problem. NAVCE 7.51 included a fix for users who continue to encounter this problem after upgrading to 7.5. See the article How to obtain an update or an upgrade for your Symantec Corporate product for instructions on receiving the latest inline release.
In other instances, this error message will indicate a genuine problem with the environment within which NAVCE is running. While not very informative, the error message seems to occur in relation to user rights and permissions under NT and domains or policy restrictions.
The first check should be to make sure that the Norton AntiVirus service is set to Local System account and "Allow service to interact with desktop."
To check the service setting
If you do not have a later build of NAVCE 7.6, or if the latest build does not solve the problem, then try the following workarounds. (In the following list, you will first see the cause of the error and then the steps you should take to solve it.)
