Hi, Im trying to install SCE agent on SCE from the pending management view. When im trying to install the agent i recieve the following errror The MOM Server failed to perform specified operation on computer PC-111130 Operation: Agent Install Install account: Domain/ ADMIN Error Code: 80070057 Error Description: The parameter is incorrect. Any ideas?

Hello Laith, Is it a new installed SCE 2007 server? Is there any agent can be installed properly? Here are some general steps to troubleshoot the agent installtion failed in the thread below: Failed Agent Installation http://social.technet.microsoft.com/Forums/en-US/systemcenterdeployment/thread/1977cbbb-1969-4a95-b011-7bcc8b79ca44 Please check if it helps. Besides, did you try to install the agent manually? Please follow the guidance line below to get the momagent.log file: 1. Copy the MOMagent.msi file from the SCE server. Usually, the MOMagent.msi file can be found under the "C:\Program Files\System Center Essentials 2007\AgentManagement\x86"; 2. Run the following command line to manually install the agent on your client machine: "MOMAgent.msi /L*V c:\momagent.log"; 3. Follow the installation wizard and input the proper SCE Server, Management Group Name, and the Agent Action Account; 4. If the installation failed, please post the c:\momagent.log file here for further analysis. Thanks,Yog Li TechNet Community Support

Thanks for your replay Yog. I installed the agent manually without any problems. But when im trying to install the agent from SCE then i got the above error. Any suggestions?
