用keytool检察或倒入Windows2000的证书服务器根证书出错？

[lpjmarco]

我用Windows2000的证书服务器颁发证书，根证书存为Base64编码，文件名为ca.cer，另外又给一个服务器颁发了证书，文件名存为server1.cer。

使用java自带的keytool时出现下列现象：
1、keytool -v -printcert -file ca.cer报错；
2、keytool -v -printcert -file server1.cer却没有出错；
3、ca.cer可以双击打开查看证书，用记事本打开后看应该格式没有错：

不知是何原因，有没有人碰到过这种情况？


附：keytool -v -printcert -file ca.cer报错信息：
