Some clients has connected but can't report inventory

Hello.
I install 3.2 Server on my XP and turn off Firewall.
Then I run lsclient.exe Servername for 179 PC and Servers in my intranet. Finally, I have 108 workstation, 27 servers and 44 not scanned systems (XP and 2003) with RPC error (HRESULT: 0x800706BA).
Testconnection say, that all OK.
DNS forward and reverse is OK, Firewall is OFF, DCOM is enabled, File sharing is enabled, simple sharing is absent in my options.
Errorlog contains:
System.Runtime.InteropServices.COMException (0x80072116): Преобразование имен: не удается найти имя или права на чтение имени недостаточны. (Исключение из HRESULT: 0x80072116)

Finally I have a lot of incorrect PTR records in R-DNS Zone. After correcting most problem was resolved.

Does this mean that your problems are solved now?

For the kerberos errors:

Could you try a "dcdiag /e /q" to check for active directory errors in your forest please.

Firstly, I moved LSweeper service from XP to 2003 Server.
After that I rerun lsclient servername and have many error about kerberos

The kerberos client received a KRB_AP_ERR_MODIFIED error from the server NAME1$. The target name used was RPCSS/name2.domain. This indicates that the password used to encrypt the kerberos service ticket is different than that on the target server. Commonly, this is due to identically named machine accounts in the target realm (DOMAIN), and the client realm. Please contact your system administrator.

Finally I have a lot of incorrect PTR records in R-DNS Zone. After correcting most problem was resolved.

I took win2k3 sp2 R2 server, stopped Windows Firewall service, ran "ipconfig /registerdns", ran "lsclient.exe Servername". RPC error (HRESULT: 0x800706BA)
I tested server with WMIdiag tool from MS -> server has errors only with "Root\servicemodel" security ACL.
UPD: All computers in remote branch report RPC error (HRESULT: 0x800706BA).
UPD2: System event log has errors: DCOM was unable to communicate with the computer <computer name> using any of the configured protocols (source-DCOM, id-10009).

Could you try the following on one of the clients that's not working. (as a test)
-stop the firewall service
-run "ipconfig /registerdns"
-run lsclient.exe and see if the scanning works this time.
