各位高手，我只是菜鸟，单位有一套管理软件，后台是SQL SERVER2000,应用表中的数据，每个表不超过20000条。系统一直从2005年用到现在，以前从未出现过错误，这几天出现了如下问题，还请各位高手给我指点一下，不胜感激。
系统登录提示如下错误，“运行时错误６，溢出”。我理解是因为ID字段类型为INT型，数值达到临界点。不知道对不对。
查看系统表　(以下每个系统表中的数据均不超过20000条)
syscolumus ID（INT数据类型）字段的最大值已经为 2146158741
Syscomments ID（INT数据类型）字段的最大值已经为 2146822710
sysdepends ID（INT数据类型）字段的最大值已经为 2137058649
sysindexes ID（INT数据类型）字段的最大值已经为 2144830803
sysindexkeys ID（INT数据类型）字段的最大值已经为2144830803
sysobjects ID（INT数据类型）字段的最大值已经为 2146822710
syspermissions ID（INT数据类型）字段的最大值已经为 2136394680
这些系统表中的ID字段值均已要达到INT数据类型的临界值。在登录系统时，通过事件探查器查看到如下信息（探查器另存为SQL）：
