Summary :
This SAP Note identifies various symptoms observed across several SAP system releases, notably post-upgrade scenarios. Users may experience extended hangs during login or logout, poor SAPgui performance, repetitive hostname resolution attempts, and saturated dialog work processes. The core issue lies in host and IP address resolutions managed by the local operating system, impacting SAP's R/3 System due to DNS misconfigurations or delays. Solutions include disabling DNS on application servers, manual hostname entries, and optimizing DNS configuration to ensure quick resolution by having proper zones and removing unnecessary external DNS queries.
