Endpoint protection errors and warning in windows server 2008

Check the dcom permissions once.
You can refer below doc

http://service1.symantec.com/support/ent-security.nsf/854fa02b4f5013678825731a007d06af/3f862957b21b671588256c620077a200?OpenDocument

You can try by upgrading the
client to RU5 also. It is the latest version and the only version which Symantec
is officially supporting with windows 2008.....

The latest version of endpoint RU-5 has better compatibility with Windows 2008. I would suggest you to upgrade to the latest version and if the issue still persists please let us know.

I am not familiar with the termology of RU-5. 

I will uninstall 11.0.3 and install 11.0.5 and see what errors/warning I get.

Restart the server once and see any errors are present..
Also tell us the role of this server.... 

Server was restarted, The Event ID 1530s continues:

today 10:16AM

Refer the following docs and assure you had done all
settings correctly

In regard to the first link, there is no evidence of DHCP problem so I ignore this link
for now.
http://service1.symantec.com/SUPPORT/ent-security.nsf/docid/2007101210172548

The last two links are regarding the same subject. The last link states: Any antivirus
vendor should provide specific instructions to correctly configure their product to work
with domain controllers that are running versions of Windows Server and that have Active
Directory Domain Services (AD DS) installed. Does someone know if Symantec has such a
document?

Since both link 2 and 3 refer to the same subject and it is difficult to compare the
documentation, I will just select the second link since it is dated later.

The next problem is that link 2 is just general information and there is no specifics on
how to exclude files/folders from scaning.

The Endpoint Protection documents seem to be located at
http://www.symantec.com/business/support/documentation.jsp?language=english&view=manuals&pid=54619

Still  the problem is locating which of the many documents and which of many pages shows
how to exclude the files mentioned in the second link. I do see the Administrator manual
is 625 pages.

In my 2nd link it is telling about the scanning exceptions for certain files and directories. You can exclude those… Many of those SEP will exclude automatically .First you confirm is it happens. If no do it manually.

For creating exception refer the link below

On second thought I question the direction this thread is taking. Here is the 1:16PM event ID 1530

Note the Printers. This appears to be a problem between printers and Endpoint Protection.
The event was recorded at 1:16:22 PM. Looking at the DCHP leases, none of the more than 20 leases today occurred during the time of Event ID 1530.

If the problem is scanning files that should not be scanned then the problem should be during scaning and the scan was not occuring during the Event ID 1530s. This doesn't mean that the file/folder exclusion (once I figure how to do that) should not be done as that may prevent other problems.

Any way you consider also the
exclusions in earlier links also. At least it will avid future problems.

I didn't see anything in the links that I thought would help. The links were for different type of problems.
