Question : Issues after removing SMS 2003 Management point

Hi All.  We have a child site, Site C which acts as a proxy-MP and a DP. It also serves as a CAP /Site Server/Component Server.   We must remove the MP role and I just did this on the central site console. We will then re-assign all of site C's clients to the parent site, Sit B by adding the Site C subnet to the Site B's boundaries.   The site C DP must remain for SMS clients at site C.    Is it that simple?  I checked on the Site C IIS server and it removed all SMS roles for the site.  

Do I need to do anything else to finish this? Any other cleanup?  On the central site console I am getting errors in component manager for site C:

Error 4192:  Systems Management Server cannot update the already existing object "cn=SMS-MP-SiteC-SMSC01" in Active Directory.

Possible cause: This site's SMS Service account or the site server's machine account may not have full control rights for the "System Management" container in Active Directory
Solution: Give the site's SMS Service account full control rights to the "System Management" container, and all child objects in Active Directory.

and a few minutes later:

Error 4195: Systems Management Server cannot delete the object "cn=SMS-MP-SiteC-SMSC01" in Active Directory.

Do I need to manually delete AD objects in the 'System Management' container?  Any suggestions?

your isp is correct. they are not dropping ICMP traffic. However their devices do not generate ICMP error messages. Traceroute uses a technique that sends an IP datagram with a TTL of 1, then it increases the TTL on the second packet.
A device receiving the datagram would reply with ICMP TTL expired or port unknown. However it can choose not to reply to these datagrams as part of their security policy.
